32.

The charge of one coulomb is equal to:

 [A]. 6.24 x 10−18 electrons [B]. one ampere [C]. one second [D]. 6.24 x 1018 electrons

Explanation:

No answer description available for this question.

 Mr. Mitchell said: (Mar 24, 2011) The coulomb unit is 6. 25x10^18 in the electronics fundamentals fifth edition.

 Pandu said: (Jun 1, 2011) 1e=1.6*10^-19columbs. So , 1q=1/(1.6*10^-19)electrons. So q=6.25*10^18 electrons.

 Praveen Thappily said: (Jun 3, 2011) The charge of one electron = 1.6 x 10^-19C Therefore, to make a charge of 1C, we need 1/ 1.6 x 10^-19 = 6.25 6 x 10^18 electrons.

 Shubhangi said: (Mar 6, 2014) Sir, value of one coulumb constant or variable. Please tell right answer.

 Suracece said: (Jan 2, 2015) 1 coulumb = 1.602*10^18 electrons.

 Pavitra said: (Feb 20, 2015) Yes the value of one coulomb is constant. 1 coulomb = 6.25*106^18 electron.

 Joseph Ramki said: (Jul 14, 2015) All atoms electron contains 1.6x10 power -19c charge only? Please clear my doubt!

 Gopala Krishna said: (Dec 29, 2015) No. of electrons = ? Charge (C) = 1 charge in one electron = 1.6*10^-19. So, n = Q/e = 1 C/1.6*10^-19 = 6.25810^18.
