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.

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 ...

Electric Potential Difference: Students learn to describe changes in the potential and kinetic energy of a point charge as it moves in an electrical field. Potential difference is introduced in terms ...

The topic of electricity often poses difficulties for many secondary school students in physics lessons. Researchers have now developed and empirically evaluated a new, intuitive curriculum as part of ...

I hope that you are never in a situation in which you are in danger from a downed, but live, power line. However, if that ever happens, the recommended safety procedure is to move away with tiny, ...
