A 100Omega resistance and a capacitor of...

A `100Omega` resistance and a capacitor of `100Omega` reactance are connected in series across a 220 V source. When the capacitor is `50% charged, the peak value of the displacement current is

A

2.2 A

B

`11A`

C

4.4 A

D

11`sqrt(2)A`

Text Solution

Verified by Experts

The correct Answer is:
A
`X_(C)=100`
`R=100`
`Z=sqrt((100)^(2)+(100)^(2))=100sqrt(2)`
`I=(E)/(Z)=(220)/(100sqrt(2))=(2.2)/(sqrt(2))`
`I_(0)=sqrt(2)I=(2.2)/(sqrt(2))xxsqrt(2)=2.2A`
