Question

A series L-C circuit has L = 0.405 H and . The resistance R is zero. Find the frequency of resonance.    

Solution

Correct option is

50 Hz

The natural frequency of the L-C series circuit is given by 

             

                 

The resonance in the circuit occurs when an a.c. voltage of frequency equal to its natural frequency is applied. Thus, the frequency of resonance is 50 Hz.
