Q. Pick out the false statement from the following
A) The direction of eddy current is given by Fleming’s right hand rule
B) A choke coil is a pure inductor used for controlling current in an a.c circuit
C) The energy stored in a conductor of capacitance $C$ having a charge $q$ is $\frac{1}{2}\frac{q^{2}}{C}$
D) The magnetic energy stored in a coil of self-inductance $L$ carrying current is $\frac{1}{2}LI^{2}$
Explanation
(a) Direct formula : (energy density $= \frac{1}{2}\varepsilon_{0}E^{2}$) $\times$ volume
