In between ELF... WebThis is called the open circuit potential of the circuit. Because there is no current there will be no lost volts so this value is the EMF of the cell. So the point where the line meets the...
WebThe emf of the cell is always greater than its terminal voltage; Since the potential drop across the cell caused by its low internal resistance, the emf of a cell is higher than its terminal voltage. Thus, due to low internal resistance, the cell's emf is greater than the terminal voltage. Suggest Corrections. 3. WebEmf of a cell is the total potential difference between the two electrodes. The potentiometer doesn’t draw current from the source of voltage. It is used to measure the internal resistance of a cell and to compare two emf. Back emf or induced emf resists the change in current in an electric circuit. This back emf is responsible for voltage ...
