Electric power
Electric power is defined as the rate of consumption of energy or simply the rate of doing work.
i.e., power (P) =
Work done (W) /Time(T)
. (i)
The work done by current (I) when it flows in a potential (V) for time (t)can be given by
W = VIt .(ii)
⇒ Power, (P) =
Vlt/t
= VI
∴ Electric power orP = VI

Electric power is defined as the rate of consumption of energy for simply the rate of doing work.
P= W/T. ...(¡)
W= VIT ...(¡¡)
=> P = VIT/T
P = VI
