Electrostatic Potential and Capacitance Quiz

Electric potential is a scalar quantity that represents the potential energy per unit charge at a point in the electric field.

Electric potential is related to the electric field through the equation E = -∇V, where E is the electric field and V is the electric potential.

The electric field around a charge can be described by electric field (E) and by electric potential (V).

<p>Potential difference is the amount of work done in moving a unit positive charge from one point to the other against the electrostatic forces. Its units are volts (V).</p> Signup and view all the answers
