### 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}
