2. Power
Electrical Power (P) is the rate at which electrical energy
is produced or consumed in a given time.
It is the amount of electricity required to start a device or
operate a load for one second.
3. Power
The unit of measurement for electrical power is the
Watt (W). One watt is equivalent to one joule per
second (J/s).
Formula: P = E / t

5. Power
Electrical Power (P) is also defined as the amount of
electric current flowing due to an applied voltage.
A second formula used to find electrical power is written
as:
Formula: P = (I)(V)
