This equation can be used to calculate what the output might be from a particular transformer, or to work out how to design a transformer to make a particular potential difference (pd) change: \(\frac ...

The electric potential at any point in space made by a point charge Q is presented by the formula given below. It is the electric potential energy per unit charge. The electric potential at any point ...

I have been asked to demonstrate some electrical things to a GCSE student. One of the things on the syllabus is potential difference, and another is EMF – electromotive force. I had always assumed ...
