Electromotive force and potential difference: introduction 1
Electromotive force is the energy required to drive electrical charges through a conductor. A cell is the device that produces electrical potential difference at the ends of the conductor. The cell or the battery does the work of pumping charges to a high potential so that they can flow. The higher the potential difference (p.d), the stronger the current in the circuit while all other factors are…
