Question

Internal resistance of a cell is the resistance offered by which component?

Options

• The conducting wires in the external circuit

• The external resistor connected to the cell

• The electrolyte of the cell when current flows through it

• The electrodes of the cell

Answer 1

Internal resistance arises from the electrolyte material between the electrodes. It represents the opposition to current flow within the cell itself due to the ionic resistance of the conducting solution or paste, and is an inherent property of the cell.
