Differentiate between power and energy used in electrical circuit and state the units for each?

Power is the rate at which energy is transferred or converted in an electrical circuit. It is measured in watts (W) and is calculated as the product of voltage (V) and current (I) in the circuit.

Energy, on the other hand, is the total amount of work done or potential for work in an electrical circuit. It is measured in watt-hours (Wh) or joules (J) and is calculated by multiplying power by time.

In summary, power is the rate at which energy is used or transferred in a circuit, while energy is the total amount of work done in the circuit. The units for power are watts (W) and for energy are watt-hours (Wh) or joules (J).

Power is the rate at which electrical energy is transferred or consumed. It is measured in watts (W).

Energy is the total amount of electrical work done or consumed over a period of time. It is measured in joules (J).

Relationship between Power and Energy:

Energy (J) = Power (W) × Time (s)

Units:

- Power: Watts (W)
- Energy: Joules (J) or kilowatt-hours (kWh)

Note:

1 kilowatt-hour (kWh) is equal to 3.6 million joules.
