PhysicsEMI/ACAC current and voltageEasy2 minPYQ_2008

PhysicsEasysingle choice

In an a.c. circuit the e.m.f. (e) and the current (i ) at any instant are given respectively by $e = E_{0} sin ω t i = I_{0} sin (ω t - ϕ)$ The average power in the circuit over one cycle of a.c. isNEET 2008 (Mains)

Options:

Answer:

Solution:

Since phase difference between current and e.m.f is $ϕ$ $∴ P_{aV} = \frac{E _{0} l _{0}}{2} cos ϕ$
