Difference between terminal voltage and emf
WebEMF is the work done by the cell in moving a coulomb of charge across its terminals. It represents the energy transferred per coulomb to the charges. Some of this energy is lost as heat due to internal energy. Hence the net … WebApr 5, 2024 · Complete answer: Let V be the terminal voltage and E be the emf. Having a load R and current flowing I and internal resistance r can be calculated as –. I = E R + r. And the potential difference across the terminal voltage calculated as: V = I. R = E R R + r. Additional Information: The terminal voltage of a battery is less than the ...

WebJun 28, 2024 · Voltage follows the non-coulomb force operation. EMF depends upon change in magnetic field (in generator), chemical energy (in battery), light intensity (in PV cell), etc. Voltage between two points depends upon the current and resistance between the two points. EMF is the cause of voltage between two points. WebIt refers to the potential difference that exists between two points in a circuit, which is responsible for the flow of electric current. EMF is measured in volts and is denoted by the symbol E. In this essay, we will explain the concept of EMF and compare it to the terminal voltage of a battery.
