voltaic cell

The enormous value of the Voltaic cell in building up the science of electricity need hardly be pointed out.

This kind may also be noted in the voltaic cell and the charged condenser, and in a chemical form in coal and gunpowder.

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

In the voltaic cell the chemical action of the acid upon the zinc transforms chemical energy into electrical energy.

In the illustration, the tubes Cu and Zn correspond to the conducting plates of copper and zinc of a voltaic cell.
