In a circuit shown in figure. What will be the readings of a voltmeter and ammeter, if AC source of 220 V and 100 Hz is connected ?

Options

A. 800 V, 2A
B. 300 V,2A
C. 220 V,2.2 A
D. 100 V,2 A

Answer

C

Explanation

In figure, `e_(L)=e_(C)`
`therefore e=sqrt(e_(R)^(2)+(e_(L)-e_(C))^(2))`
`therefore e=e_(R)=220V`
Now in figure `e_(L)=e_(C)` and the circuit is series circuit therefore `I_(L)=I_(C)` and hence `X_(L)=X_(C)`
If `X_(L)=X_(C)` then Z=R
`therefore I=(e)/(Z)=(e)/(R)=(220)/(100)=2.2A`
