Answer 2

Electric cell:

• The device which converts chemical energy into electrical energy is known as electric cell.
• Cell is a source of constant emf but not constant current.

Emf of cell (E):

• The potential difference across the terminals of a cell when it is not supplying any current is called it's emf.

Potential difference (V):

• The voltage across the terminals of a cell when it is supplying current to external resistance is called potential difference or Terminal voltage.

Internal resistance (r):

• In case of a cell the opposition of electrolyte to the flow of current through it is called internal resistance of the cell.
