Question

In the given circuit, Fig., the reading of voltmeter `V_(1)` and `V_(2)` 300 votls each. The reading of the voltemeter `V_(3)` and ammeter `A` are respectively

A. `150V,2.2A`
B. `220 V,2.2 A`
C. `220V,2.0 A`
D. `100 V,2.0 A`

Answer 1

Correct Answer - B
For series `LCR` circuit
voltage `V=sqrt(V_(R)^(2)+(V_(L)-V_(C))^(2))`
Since `V_(L)=V_(C)` hence `V=V_(R)=200 V`
Also, current `i=V/R=220/100=2.2 A`
