An LCR series circuit consists of a resistance of a `10 Omega` a capacitance of reactance `60 Omega` and an inductor coil The circuit is found to resonate when put across a `300 V ,100 ` Hz supply The inductance of the coil is `(taken pi =3)` .

Options

A. `0.1H`
B. `0.01H`
C. `0.2H`
D. `0.02H`

Answer

A

Explanation

`X_(L) = X_(C) implies omegaL =X_(C)`
`2pi f L =X_(C)`
`2pi xx 100 L = 60`
`2 xx 3xx 10 L = 60 implies L = 0.1 H` .
