Question

The reading of ammeter and voltmeter in the following circuit are respectively

A. 2 A , 200 V
B. 1.5 A , 100 V
C. 2.7 A, 220 V
D. 22 A, 220 V

Answer 1

Correct Answer - D
(d) `V = sqrt (V_(R)^(2) + (V_(L)-V_(C))^(2))`
`because V_(R) = V `
`because V_(L) = V_(C)`
`therefore` Reading of voltmeter = 200V
Reading of ammeter, `I_(rms) = E_(rms)/Z = 220/100 = 2.2 A`
