Work between an electric dipole?

Question

How would I compute the amount of work involved in transferring a charge of two coulombs:

a) from one electrode to the other electrode?

b) from one electrode to the other electrode at a 45-degree angle?

c) from one electrode to the other and then back to the first one?

Voltage = 2V

Would you obtain different results if you were to use different types of electrodes?

Thank you for your help!

Answer 1

Work = QΔV, regardless of the route taken or the type of electrode. (See ref.)

This should answer A and B.

For C, the net work = Q*net ΔV = 0.
