Question
In the series LCR circuit as shown in figure, the voltmeter and ammeter readings are :
Options
A.V = 100 volt, I = 2 amp
B.V = 100 volt, I = 5 amp
C.V = 1000 volt, I = 2 amp
D.V = 300 volt, I = 1 amp
Solution
At resonance (VC = VL)
V = Irms × R
=
× R (here z = R)
V = Vrms = 100 volt & Irms =
= 2 Amp.
V = Irms × R
=
× R (here z = R) V = Vrms = 100 volt & Irms =
= 2 Amp. Create a free account to view solution
