Find the reactance of a capacitor (C = 2...

Find the reactance of a capacitor `(C = 200 muF)` when it is connected to (a) `a 10 Hz AC source`, (b) `a 50 Hz AC` source and ( c) `a 500 Hz AC` source.

Text Solution

Verified by Experts

`(a) X_(c)=(1)/(omegaC)=(1)/(2pifC)cong 80Omega "For" f=10Hz "AC source"`
`(b) X_(c)=(1)/(omegaC)=(1)/(2pifC)cong 16Omega "For" f=50Hz and`
`(c) X_(c)=(1)/(omegaC)=(1)/(2pifC)cong 1.6Omega "For" f=500Hz`
