the relationship bitween the electromotive force, the current, and the resistance was discoverd by a German scientist,George Simon Ohm,at the beginning of the nineteeth centuy. The unit of resistance was namede in his honor.
This relationship, which is called Ohms law, can be expressed mthematically by means of the following formula:
Current=electromotive force/resistance or I=E/R
where I is measured in amperes, E in volts, and R in ohms. This means that the greatre the electoromotive force is , the greater will be the current: and the greater the resistance, the smaller the current.
