Question

differentiate the terminal voltage and emf of a cell

Answer 1

voltage:only parent when circuit is closed
determines speed of electrons
effected by resistance and current


emf::present even when circuit is closed
determines the amount of voltage from current
effected by internal and external resistance too..


emf:work done in bringing a positive charge from negative to positive terminal

terminal voltage or potential difference :: work done in bringing a charge from point A to point B
