It can also be defined as the potential difference between the two terminals of the cell in closed circuit (i.e. when current flows). It is denoted by ... ghoulish bunny studiosWebIt represents the energy transferred per coulomb to the charges. Some of this energy is lost as heat due to internal energy. Hence the net energy gained by the charge = the emf - heat lost. This net energy gained per coulomb is called the terminal voltage. This is the voltage across the ends of the battery. Created by Mahesh Shenoy. froppy plushieWebPart 4 is an extension to the experiment. Use a battery with artificially increased internal resistance concealed in a box. Add more and more lamps in parallel, and note the potential difference between the terminals.
