A 10 ohm resistance, 5 mH coil and 10mu ...

A `10` ohm resistance, `5 mH` coil and `10mu F` capacitor are joined in series. When a suitable frequency alternating current source is joined to this combination, the circuit resonates. If the resistance is halved, the resonance frequency

Is halved

Is doubled

Remain unchanged

In quadrupled

Text Solution

Verified by Experts

The correct Answer is:

Resonant frequency `=1/(2pisqrt(LC))` does not depend on resistance.
