# Resonance and its applications

### Explanation of question 6

In Fig. 10.1, the supply frequency is varied. At the resonant frequency the two voltmeters will read

1. zero
2. different values
3. the same low value
4. the same high value

The answer is :- 4 At resonance, the reactance of L will be equal to that of C, thus an equal voltage will appear across the two components. The voltages will be high because of the voltage magnification.
