Question

How does a cell or a battery cause current in the electric current ?

✓

Answer

Electric cell or a battery is a source of electrical energy. The chemical reaction going in the cell develops potential difference between its two terminals. So when this cell is connected in a closed circuit, it supplies energy to the electrons (mobile charge carriers) in the circuit. Hence electrons are being pushed to cause the flow of electric current.
