Summary Chapter 12 Class 10 Science

  • A stream of electrons moving through a conductor constitutes an electric current. Conventionally, the direction of current is taken opposite to the direction of flow of electrons.
  • The SI unit of electric current is ampere.
  • To set the electrons in motion in an electric circuit, we use a cell or a battery. A cell generates a potential difference across its terminals. It is measured in volts (V).
  • Resistance is a property that resists the flow of electrons in a conductor. It controls the magnitude of the current. The SI unit of resistance is ohm (Ω).
  • Ohm’s law: The potential difference across the ends of a resistor is directly proportional to the current through it, provided its temperature remains the same.
  • The resistance of a conductor depends directly on its length, inversely on its area of cross-section, and also on the material of the conductor.
  • The equivalent resistance of several resistors in series is equal to the sum of their individual resistances.
  • A set of resistors connected in parallel has an equivalent resistance Rp given by, 1/Rp = (1/R1) + (1/R2) + (1/R3) + ……… + (1/Rn)
  • The electrical energy dissipated in a resistor is given by: W = V × I × t
  • The unit of power is watt (W). One watt of power is consumed when 1 A of current flows at a potential difference of 1 V.
  • The commercial unit of electrical energy is kilowatt hour (kWh). {1 kWh = 3,600,000} {J = 3.6 × 10^6J}

Summary Chapter 10 Class 10 Science

  • Light seems to travel in straight lines.
  • Mirrors and lenses form images of objects. Images can be either real or virtual, depending on the position of the object.
  • The reflecting surfaces, of all types, obey the laws of reflection. The refracting surfaces obey the laws of refraction.
  • New Cartesian Sign Conventions are followed for spherical mirrors and lenses.
  • Mirror formula, (1/v)+(1/u)=1/f, gives the relationship between the object-distance (u), image-distance (v), and focal length (f) of a spherical mirror.
  • The focal length of a spherical mirror is equal to half its radius of curvature.
  • The magnification produced by a spherical mirror is the ratio of the height of the image to the height of the object.
  • A light ray travelling obliquely from a denser medium to a rarer medium bends away from the normal. A light ray bends towards the normal when it travels obliquely from a rarer to a denser medium.
  • Light travels in vacuum with an enormous speed of 3×10^8 m/s. The speed of light is different in different media.
  • The refractive index of a transparent medium is the ratio of the speed of light in vacuum to that in the medium.
  • In case of a rectangular glass slab, the refraction takes place at both air-glass interface and glass-air interface. The emergent ray is parallel to the direction of incident ray.
  • Lens formula, (1/v)+(1/u)=1/f, gives the relationship between the object-distance (u), image-distance (v), and the focal length (f) of a spherical lens.
  • Power of a lens is the reciprocal of its focal length. The SI unit of power of a lens is dioptre.

Summary Chapter 13 Class 10 Science

  • A compass needle is a small magnet. Its one end, which points towards north, is called a north pole, and the other end, which points towards south, is called a south pole.
  • A magnetic field exists in the region surrounding a magnet, in which the force of the magnet can be detected.
  • Field lines are used to represent a magnetic field. A field line is the path along which a hypothetical free north pole would tend to move. The direction of the magnetic field at a point is given by the direction that a north pole placed at that point would take. Field lines are shown closer together where the magnetic field is greater.
  • A metallic wire carrying an electric current has associated with it a magnetic field. The field lines about the wire consist of a series of concentric circles whose direction is given by the right-hand rule.
  • The pattern of the magnetic field around a conductor due to an electric current flowing through it depends on the shape of the conductor. The magnetic field of a solenoid carrying a current is similar to that of a bar magnet.
  • An electromagnet consists of a core of soft iron wrapped around with a coil of insulated copper wire.
  • A current-carrying conductor when placed in a magnetic field experiences a force. If the direction of the field and that of the current are mutually perpendicular to each other, then the force acting on the conductor will be perpendicular to both and will be given by Fleming’s left-hand rule. This is the basis of an electric motor. An electric motor is a device that converts electric energy into mechanical energy.
  • The phenomenon of electromagnetic induction is the production of induced current in a coil placed in a region where the magnetic field changes with time. The magnetic field may change due to a relative motion between the coil and a magnet placed near to the coil. If the coil is placed near to a current-carrying conductor, the magnetic field may change either due to a change in the current through the conductor or due to the relative motion between the coil and conductor. The direction of the induced current is given by the Fleming’s right-hand rule.
  • A generator converts mechanical energy into electrical energy. It works on the basis of electromagnetic induction.
  • In our houses we receive AC electric power of 220 V with a frequency of 50 Hz. One of the wires in this supply is with red insulation, called live wire. The other one is of black insulation, which is a neutral wire. The potential difference between the two is 220 V. The third is the earth wire that has green insulation and this is connected to a metallic body deep inside earth. It is used as a safety measure to ensure that any leakage of current to a metallic body does not give any severe shock to a user.
  • Fuse is the most important safety device, used for protecting the circuits due to short-circuiting or overloading of the circuits.

Summary Chapter 2 Class 10 Science

  • Acid-base indicators are dyes or mixtures of dyes which are used to indicate the presence of acids and bases.
  • Acidic nature of a substance is due to the formation of H+ (aq) ions in solution. Formation of OH– (aq) ions in solution is responsible for the basic nature of a substance.
  • When an acid reacts with a metal, hydrogen gas is evolved and a corresponding salt is formed.
  • When a base reacts with a metal, along with the evolution of hydrogen gas a salt is formed which has a negative ion composed of the metal and oxygen.
  • When an acid reacts with a metal carbonate or metal hydrogen carbonate, it gives the corresponding salt, carbon dioxide gas and water.
  • Acidic and basic solutions in water conduct electricity because they produce hydrogen and hydroxide ions respectively.
  • The strength of an acid or an alkali can be tested by using a scale called the pH scale (0-14) which gives the measure of hydrogen ion concentration in a solution.
  • A neutral solution has a pH of exactly 7, while an acidic solution has a pH less than 7 and a basic solution a pH more than 7.
  • Living beings carry out their metabolic activities within an optimal pH range.
  • Mixing concentrated acids or bases with water is a highly exothermic process.
  • Acids and bases neutralize each other to form corresponding salts and water.
  • Water of crystallization is the fixed number of water molecules present in one formula unit of a salt.
  • Salts have various uses in everyday life and in industries.

Summary Chapter 15 Class 10 Science

  • The various components of an ecosystem are interdependent.
  • The producers make the energy from sunlight available to the rest of the ecosystem.
  • There is a loss of energy as we go from one trophic level to the next, this limits the number of trophic levels in a food-chain.
  • Human activities have an impact on the environment.
  • The use of chemicals like CFCs has endangered the ozone layer. Since the ozone layer protects against the ultraviolet radiation from the Sun, this could damage the environment.
  • The waste we generate may be biodegradable or non-biodegradable.
  • The disposal of the waste we generate is causing serious environmental problems.

  • We also need to look for new sources of energy because the conventional sources of energy like fossil fuels are in danger of getting exhausted soon.
  • The energy source we select would depend on factors like the ease and cost of extracting energy from the source, the efficiency of the technology available for using that source of energy and the environmental impact of using that source.
  • Many of the sources ultimately derive their energy from the Sun.
