Electricity is controllable and convenient for diverse applications in homes, schools, hospitals, and industries.

Overloading can occur due to an accidental increase in supply voltage or by connecting too many appliances to a single socket.

Short-circuiting occurs when the live and neutral wires come into direct contact due to damaged insulation or appliance faults.

One volt is the potential difference between two points in a current-carrying conductor when 1 joule of work is done to move a charge of 1 coulomb from one point to the other.

The SI unit of electric potential difference is the volt (V), named after Alessandro Volta, an Italian physicist.
