The work done in moving a charge of 2 coulomb (C) from point A to point B is 24 J. What is the potential difference between A and B?

Two conducting wires of the same material and of equal lengths and equal diameters are first connected in parallel and then in series in a circuit across the same potential difference. The ratio of heat produced in parallel and series combinations is
