An inductor of 0.5 mH , a capacitor of 20 F and a resistance of 20 are connected in series with a 220 ~V a.c. source. If the current is in phase with the e.m.f. the maximum current in the circuit is x A . The value of ' x ' is

Options

  1. A44
  2. B82
  3. C146
  4. D242

Correct answer

D. 242

Step-by-step solution

When current is in phase with voltage, we have aligned & Z = R =20 & e ₀= 2 e _ rms =220 2 ~V & i ₀= e ₀ Z = 220 2 20 =11 2 ~A & i ₀= 242 ~A aligned
