Solution
An electric cell is a device that converts chemical energy into electrical energy.
An electric cell always does the work to maintain the flow of electric charge in the electrical circuit. This is why the electric cell gets discharged.
The work done by the cell to maintain the flow of charge in the circuit is called electrical work or electrical energy.
So, the electric cell is a device that maintains the flow of current in the electrical circuit.
