A series RLC circuit has a resonant frequency of 1000 Hz. The maximum voltage across C is likely to occur at a frequency of about
-
A network has two branches in parallel. One branch contains impedance Z1 and the other branch has impedance Z2. If it is fed from an ac voltage V of frequency f, the current through Z1 depends, on

In the given circuit, viewed from AB, the circuit can be reduced to an equivalent circuit as
-
An RC series circuit is charged by a voltage E. After a long time the battery is removed and a short circuit is placed across R-C. Then
-
Two coils having self inductances of 10 mH and 40 mH are mutually coupled. The maximum possible mutual inductance is

7 V.
Therefore current through 2Ω resistance is 11 A. Voltage across R = 48 - 10 - 11 x 2 = 16 V.
