How many electrons flow when a current of 5 amp is passed through a cell for 200 sec?

Options

  1. A9.65 10²¹
  2. B1 60 10²¹
  3. C3 12 10²¹
  4. D6 24 10²¹

Correct answer

D. 6 24 10²¹

Step-by-step solution

Q = I t =5 200=1000 C The charge of one electron is 1.602 10⁻¹⁹ C No. of electrons passed = 1000 C 1.602 10⁻¹⁹ C =6.24 10²¹
