... volts (V), and is generally called voltage. The voltage depends on the 'strength' of the electrical supply. In the diagram above, adding a second cell would supply a higher voltage. The amount of current will also depend on electrical resistance (or resistance). This value- in ohms (0) - is a measur ...
