Question
Define Electric power
Solution 1
Electric power is the rate of doing work or it is the work done in 1 second.
Electric Power(P) = `"Electric work (w)"/"time(t)"`
The S. I. unit of power is ‘Watt’.
If a current of 1 ampere flows through a metallic conductor at a potential difference of 1 volt, the power is said to be 1 watt.
or 1 Watt = 1 Volt × 1 Ampere.
Solution 2
Electric power (P) is the rate at which electrical energy is transferred or consumed in an electrical circuit. It can be represented by the formula
P = IV
Where:
- P is the electric power in watts (W),
- I is current in amperes (A), and
- V is the potential difference (voltage) in volts (V).
