Answer / yash

Power is the energy utilized in a particular span of time.
Calculation of power depends on the type of energy utilized.

Answer / rahul

Power is nothing but the rate of doing work.
In electrical engg., u can say it is the rate of change of
stored energy. Usually in EE,instantaneous power is given
by product of Instantaneouw V and I.

Answer / ramanharikrishnan

Multiplication of voltage and current of specific load.
It can be either watts or voltampere.

Answer / bijan

Power is rate of change of Workdone. P= (W/t)
SI Unit - Watt
Dimension : M1 L2 T-3

Answer / khilendra pant

power=V*I, Voltage is electric potential energy per unit
charge, measured in joules per coulomb ( = volts). It is
often referred to as "electric potential", which then must
be distinguished from electric potential energy by noting
that the "potential" is a "per-unit-charge" quantity. Like
mechanical potential energy, the zero of potential can be
chosen at any point, so the difference in voltage is the
quantity which is physically meaningful. The difference in
voltage measured when moving from point A to point B is
equal to the work which would have to be done, per unit
charge, against the electric field to move the charge from
A to B.

Answer / kumar.n

Power means multification of Voltage and current.
