Answer:
The emf of the cell will be 1.5 volt
Explanation:
We have given work done [tex]=2.4\times 10^{-19}j[/tex]
Charge on electron that is q , [tex]e=1.6\times 10^{-19}C[/tex]
Energy of electron is given by [tex]Energy=qV[/tex], here e is charge on electron and V is emf
[tex]2.4\times 10^{-19}=1.6\times 10^{-19}V[/tex]
V = 1.5 Volt , that is emf of the cell
So the emf of the cell will be 1.5 volt
The emf across the solar cell is 1.5 Volts.
What is emf?
The EMF or electromotive force is the energy supplied by a battery or a cell per coulomb (Q) of charge passing through it. The emf is given as,
[tex]E = \dfrac {W}{Q}[/tex]
Where E is the electromotive force, W is the work done and Q is the charge.
Given that the work done during the movement of an electron is 2.4×10−19 J and the charge Q at the electron is 1.6×10−19 C. So the emf of the solar cell is,
[tex]E = \dfrac { 2.4\times 10^{-19}}{1.6 \times 10^{-19}}[/tex]
[tex]E = 1.5\;\rm V[/tex]
Hence we can conclude that the emf across the solar cell is 1.5 Volts.
