Question

what is the function of a cell or battery in the circuit​

Answer 1

Answer:

An electrical cell is an "electrical power supply" - internally it converts stored chemical energy into electrical potential energy, allowing a current to flow from the positive terminal round to the negative one via an external circuit (this is called conventional current, which is chosen to go from + to -
