Question

What is potential difference and conventional current?

Answer 1

Potential difference is the work done per unit charge. A potential difference of 1 V means that 1 joule of work is done per coulomb of charge.

Conventional current flows around a circuit from the positive (+) side of the cell to the negative (-). However the electrons are flowing around the circuit in the opposite direction from the negative (-) side of the cell to the positive (+).
