In an a.c circuit, V & I are given by V ...

In an a.c circuit, `V` & I are given by `V = 100 sin (100 t)` volt.
`I = 100 sin (100 t + (pi)/(2)) mA`
The power dissipated in the circuit is:

A

1 watt

B

10 watt

C

zero

D

5 watt

Text Solution

Verified by Experts

The correct Answer is:
C
`P = V_("rms") I_("rms") cos phi`
`(100)/(sqrt(2)) ((100)/(sqrt(2)) xx 10^(-3)) cos 90^(@) = 0`
