In high voltage we use SF6 or VCB.Because if we go to ACB
the arc quenching will no be proper.Where as if we use vacuum
or sulfur hydrochloride the arc quenching can be 100percent.

An impedance of 100 ohms resistance and an unknown inductance is connected across the capacitor. The resulting impedance is a pure resistance of 500 ohms ifω = 10^5 rad/sec. calculate the values of inductor and capacitor.
