Question

In the circuit shown in figureure the `AC` source gives a voltage `V=20cos(2000t)`. Neglecting source resistance, the voltmeter and and ammeter readings will be
.
A. `0 V, 0.47 A`
B. `1.68 V, 0.47 A`
C. `0 V, 1.4 A`
D. `5.6 V, 1.4 A`

Answer 1

Correct Answer - D
Ammeter reading, `i = (E_("rms"))/(sqrt(R^(2) + (omega L - (1)/(omega C))^(2)))`
and `R = 4 + 6 = 10 Omega`
voltmeter reading, `V = i sqrt(R_(1)^(2) + (omega L - (1)/(omega C))^(2))` and `R_(1) = 4 Omega`
