A series LCR circuit contains inductance 5 mH, capacitance 2 mu F and resistance 10 Omega. If a frequencyA.C. source is varied, what is the frequency at which maximum power is dissipated ?

Answer»

`(10^(5))/(pi) Hz`
`(10^(-5))/(pi)Hz`
`(2)/(pi) xx 10^(5) pi Hz`
`(5)/(pi) xx 10^(3) Hz`

Solution :`f_(0) = (1)/(2pi sqrt(LC)) = (1)/(2pisqrt(5 xx 10^(-3) xx 2 xx 10^(-6))) = (10^(-4))/(2pi) = (5 xx 10^(-3))/(pi) Hz`
