what is electric power??
Answers
Electric power is the rate at which electric energy is transferred. Electric power is measured by capacity and is commonly expressed in megawatts (MW). A megawatt (MW) is one million watts.
The electric power P is equal to the energy consumption E divided by the consumption time t:
P =E/t
P is the electric power in watt (W).
E is the energy consumption in joule (J).
t is the time in seconds (s).
Example
Find the electric power of an electrical circuit that consumes 120 joules for 20 seconds.
Solution:
E = 120J
t = 20s
P = E / t = 120J / 20s = 6W
