A) \[\frac{L{{I}^{2}}}{2}\]
B) \[L{{I}^{2}}\]
C) \[\frac{L{{I}^{2}}}{4}\]
D) zero
Correct Answer: D
Solution :
The rate of dissipation of energy in an electrical circuit is called power. It is given by \[P={{i}_{rms}}\times {{E}_{rms}}\times \cos \phi \] In a purely .inductive circuit resistance is zero, then phase between current and voltage is \[90{}^\circ \]hence, average power is \[{{P}_{avg}}={{E}_{rms}}\times {{i}_{rms}}\times \cos {{90}^{o}}=0\] Hence, no energy dissipation in the circuit.
