A particle having the charge of 20 electrons falls through a potential difference of 100 volts. Calculate the energy acquired by it in electron volt (eV).
Correct answer: D. 2.0 x 10^3 eV
- A. 2.0 x 10^-2 eV
- B. 2.0 x 10^-3 eV
- C. 2.0 x 10^2 eV
- D. 2.0 x 10^3 eV
Explanation
Energy = qV= 20e x 100V= 2 x 103 eVHence, option D is the correct option.

About Current Electricity
Steady current relates charge flow to potential difference, resistance and resistivity, including how temperature changes a conductor's resistance. Sources with internal resistance have terminal voltage below their emf when delivering current, and maximum power output occurs under a specific load condition rather than at zero resistance.
