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 difference is the difference in electric potential represented by V which shortens the word volt, the unit of measurement of the difference in electromotive force (EMF) or ...

Potential difference (or voltage) is a measure of energy, per unit of charge, transferred between two points in a circuit. A potential difference of 1 volt means that 1 joule of work is done per ...

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.
