The reading of the ammeter in the following circuit is (a) 3 A (b) 6 A (c) 12 A (d) 9 A

Answer: (b). Series LCR: VL = VC = 100 V are opposite in phase, so they cancel (resonance). The whole supply voltage appears across R: VR = 300 V. I = VR/R = 300/50 = 6 A. So the answer is (b) 6 A.

The reading of the ammeter in the following circuit is

Show answer and solution

Answer: (b)

Series LCR: $V_L = V_C = 100$ V are opposite in phase, so they cancel (resonance).
The whole supply voltage appears across $R$ : $V_R = 300$ V.
$I = \dfrac{V_R}{R} = \dfrac{300}{50} = 6$ A. So the answer is (b) 6 A.
