Q. In the circuit shown in figure, a conducting wire $HE$ is moved with a constant speed $v$ towards legt. Th complete circuit is placed in a uniform magnetic field $\overrightarrow{B}$ perpendicular to the plane of circuit inwards. The current in $HKDE$ is

A) Anti-clock-wise
B) Clock-wise
C) Alternating
D) Zero
Explanation

(d) Potential difference across the capacitor = emf induced across $HE = Blv$ which is constant. Therefore, charge stored in the capacitor is constant. Hence current in the circuit $HKDE$ is zero.
