What is difference between e.m.f. and terminal voltage |
|
Answer» ELECTROMOTIVE Force (emf) is the energy (work) given by an electric cell to flow a unit charge in the whole circuit (containing cell). Terminal Voltage is the work DONE by an electric cell to flow a unit charge between TWO POINTS of a circuit. So, difference between EMF and Terminal Voltage is that EMF is measured for whole circuit WHEREAS Terminal Voltage is measured for two points of a circuit. We can say that all the Terminal Voltages of a cell form a EMF. Thus, E = V1 + V2 + V3 + V4 +..........+ Vn. ●●●●●●●●●●●●●●●●●●●●●●●●● Hope it was helpful. |
