Question

The emf of a cell is 5 volt and its internal resistance is 1 ohm. If the terminals of the cell are joined
by a resistance wire of 9 ohm, what will be the potential difference between the plates of the cell 7​

Answer 1

Explanation:

Internal resistance refers to the opposition to the flow of current offered by the cells and batteries themselves resulting in the generation of heat. Internal resistance is measured in Ohms. The relationship between internal resistance (r) and emf (e) of cell s given by. e = I (r + R)
