wika current transformer Analysis

Voltage is what makes electric charges move. It is the 'push' that causes charges to move in a wire or other electrical conductor.It can be thought of as the force that pushes the charges, but it is not a force.Voltage can cause charges to move, and since moving charges is a current, voltage can cause a current.
