The Potential Difference or Voltage Drop can be considered the voltage difference between any two points in a circuit. It is also the difference in electric potential between the final and the initial ...

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 ...

The simplest complete circuit is a piece of wire from one end of a battery to the other. An electric current can flow in the wire from one end of the battery to the other, but nothing useful happens.

Current is a measure of how much electric charge flows through a circuit. The more charge that flows, the bigger the current. Current is measured in amperes. The symbol for ampere is A. For example, ...
