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 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.

Potential difference in series circuits Try the experiment online Resistors in series Test your knowledge Resistance ® close resistance (R)How difficult it is for current to flow. increases when ...

We use batteries to supply power in several projects. The chemicals contained in the battery are converted into an electrical current, which in turn makes the battery contain the potential energy.
