gravity cell

noun

, Electricity.

gravity cell

an electrolytic cell in which the electrodes lie in two different electrolytes, which are separated into two layers by the difference in their relative densities

One of the best-known cells in which weakening of the current is prevented by chemical means is the so-called gravity cell.

The gravity cell is cheap, easy to construct, and of constant strength, and is in almost universal use in telegraphic work.

This is because the current meets more resistance within the gravity cell than within the voltaic cell.

This apparatus is good to work a gravity cell when it needs regulating.

The gravity cell has a practically constant voltage of 1.08 volts.
