1. Potential at any point on an equipotential surface is constant. So, the work done, W = V_AB.q

Here, V_AB = V_B – V_A = 0V.

2. Lightning carries with it really high value of current in the order of 10-1000 amperes, which is really fatal.

3. If there is no charge, the electric field will be continuous without being diverged from or converged into that charge. For example, if there is a positive charge, then the field will be diverged from that charge.

5. henry is the SI unit of inductance.
