Question

An ac generator `G` with an adjustable frequency of oscillation is used in the circuit, as shown.

If the ac source `G` is `100 V` rating at resonant frequency of the circuit, then average power supplied by the source is
A. `0 J`
B. `1 m J`
C. `100 mJ`
D. not possible to calcualte from the given information

Answer 1

Correct Answer - D
As 1ms time duration is very less than time period `T` at resonance, thermal energy produced is not possible to calculate without information about start of the given time duration.
