Question

the number of electrons taken out from a body to produce 1 coulomb of charge change will be

Answer 1

Given that

Charge (Q) = 1 C

Electron (e) = 1.6× 10^-19

Number of electron (n) = ?

Q= ne

1 C = n × 1.6×10^-19 C

n = 1/(1.6×10^-19)

n = 6.25 × 10^18 electron

Answer 2

Given,

• Charge 'Q' = 1 Coulomb
• e = 1.6 * 10⁻¹⁹ C

To find,

• We have to find the number of electrons taken out from a body to produce 1 coulomb of charge.

Solution,

We can simply find the number of electrons taken out from a body to produce 1 coulomb of charge by using the following formula:

         Q = ne      (*)

where 'Q' is the charge, 'n' is the number of electrons, and 'e' is the electronic charge.

Charge 'Q' = 1 Coulomb

e = 1.6 * 10⁻¹⁹ C

Then, using (*), we get

                              1 = n * 1.6 * 10⁻¹⁹

            1/1.6 * 10⁻¹⁹ = n

            6.25 * 10¹⁸ = number oof electrons

Hence,  6.25 * 10¹⁸ number of electrons are taken out from a body to produce 1 coulomb of charge.
