Electric Cell

Content

An electric cell is a device used to generate the electric force required to move the electrons through the internal and external electric circuit. There are primary and secondary cells.

1. Primary cells: Primary cells are cells that cannot be recharged. They give out electrical energy directly from its stored energy. Examples are:

(i) Simple cell

(ii) Daniel cell

(iii) Leclanche cell.

2. Secondary cells (Accumulators): they are cells which can be recharged and cannot generate electricity until electricity has been supplied to it. has been supplied to it.
