Explanation of question 9

If the circuit of Fig. 12.4 is at resonance, the p.d. across the resistor R will be

  1. less than 6V
  2. equal to 6V
  3. equal to the p.d. across the capacitor
  4. very high

The answer is :- 2

At resonance, a series tuned circuit has negligible impedance, therefore the full supply voltage will appear across the resistor R.
