as shown. Which of the following options is/are correct?
as shown. Which of the following options is/are correct?
- At w ~ 0 the current flowing through the circuit becomes nearly zero
- The frequency at which the current will be in phase with the voltage is independent of R
- The current will be in phase with the voltage if
w = 104 rad s–1. - At w > > 106 rad s–1, the circuit behaves like a capacitor.
Answer
(C) The current will be in phase with the voltage if w = 10 4 rad s –1 .
