24. In the circuit shown,
(2017 Adv.)
(a) At
(b) The frequency at which the current will be in phase with the voltage is independent of
(c) The current will be in phase with the voltage if
(d) At
Show Answer
Answer:
Correct Answer: 24. (a, b)
Solution:
- At
Further at resonance frequency, current and voltage are in phase. This resonance frequency is given by
We can see that this frequency is independent of
Further,
At,
For
