Cell phone radiation is generated WebDec 10, 2024 · Difference of potential between any two points on the circuit. E.M.F is always greater than the potential difference between any points in the circuit. This is always less than the E.M.F. Formula: E = I (R + r) Formula: V = IR. This is caused by the electric, gravitational and magnetic fields.

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 energy gained by the charge = the emf - heat lost. This net energy gained per coulomb is called the terminal voltage.
