In the series L-C-R circuit , the voltmeter and ammeter readings are

A

V = 100 V, I = 2 A

B

V = 100 V , I = 5 A

C

V = 1000 V, I = 2 A

D

V = 300 V , I = 1 A

Text Solution

Verified by Experts

The correct Answer is:
A
V = `sqrt V_R^(2) + (V_L - V_C)^(2)`
As, `V_L` = `V_C` = 400 V
`therefore` V = `V_R`
Reading of voltmeter = 100 V
Reading of ammeter, `I_rms` = `V_rms`/Z = 100/50 = 2 A.
