A capacitor of capacitance `25muF` is charged to `300V`. It is then connected across a `10mH` inductor. The resistance in the circuit is negligible.
a. Find the frequency of oscillation of the circuit.
b. Find the potential difference across capacitor and magnitude of circuit current `1.2ms` after the inductor and capacitor are connected.
c. Find the magnetic energy and electric energy at `t=0` and `t=1.2ms`.

Text Solution

Verified by Experts

The frequency of oscillation of the circuit is,`f=(1)/(2pisqrt (LC))`
Substituting the given values we have`f=(1)/(2pisqrt((10xx10^(-3))25xx10^(-6)))=318.3HZ` 20(10x10 })(25x10-6)
