The emf of the solar cell moving the electrons from the positive to the negative terminal is 1.5 V

What is electromotive force (EMF)?

The electromotive force (EMF) is defined as the energy supplied by a battery per unit charge. Mathematically, it can be expressed as:

Electromotive force (EMF) = Work (W) / charge (Q)

EMF = W / Q

How to determine the EMF

  • work (W) = 2.4×10¯¹⁹ J
  • Charge on electron = 1.6×10¯¹⁹ C
  • Electromotive force (EMF) =?

EMF = W / Q

EMF = 2.4×10¯¹⁹ / 1.6×10¯¹⁹

EMF = 1.5 V
