(a) Electric generators: voltaic cell uses chemical energy; dynamo uses mechanical energy.
In applying this illustration to the voltaic cell, we make use of Ohm's law.
The enormous value of the voltaic cell in building up the science of electricity need hardly be pointed out.
The energy of the current is kept up by the heat absorbed, just as it is kept up by chemical action in the voltaic cell.
What conditions in a voltaic cell will give a steady electromotive force.
The cell is then, when the charging current ceases, capable of acting as a voltaic cell.
The electrochemical apparatus was a voltameter containing a definite compound to be electrolysed, or a voltaic cell or battery.
This kind may also be noted in the voltaic cell and the charged condenser, and in a chemical form in coal and gunpowder.
Here C is the voltaic cell, the two lines representing the plates of the cell.
The uninjured end is therefore comparable to the zinc in a voltaic cell (is zincoid), the injured being copper-like or cuproid.
