Question

Which device is used to maintain the potential difference between two points of the conductor -rheostay,cell, voltmeter or ammeter

Answer 1

Answer:

Cell.

Explanation:

Cell is a chemical device which is used to maintain the potential difference across two points of a conductor.

Cell is made up of cathode and anode rod and an electrolysis solution is filled .The chemical reactions takes place between the two opposite electrodes is the source which converts chemical energy in to electrical energy.

The combination of cells in series combination is known as battery.

The cells is available in various shapes and sizes like button cells, dry cell,leachance cell etc.
