As V_L = V_C = 300 V, resonance will take place. V_R = 220 V. Current, I = 220 / 100.

  1. Reading of V_R = 220 V and reading of I = 2.2 A
  2. Reading of V_R = 300 V and reading of I = 3 A
  3. Reading of V_R = 200 V and reading of I = 2 A
  4. Reading of V_R = 250 V and reading of I = 2.5 A

Correct answer: Reading of V_R = 220 V and reading of I = 2.2 A

Solution

At resonance, the voltage across the resistor (V_R) equals the supply voltage, and the current (I) is given by Ohm's law. Here, V_R = 220 V and I = 220/100 = 2.2 A.
