Circuit Theory

Which of the following amount of electrons is equivalent to $-3.941$ C of charge?

a) $1.628×10^{20}$

b) $1.24×10^{18}$

c) $6.482×10^{17}$

d) $2.46×10^{19}$

Correct Answer: Option D

Solution:

As we know, $6.24×10^{18}$ electrons consitute $-1$C of charge. Hence $-3.941$C of charge has $3.941×6.24×10^{18}$ no of electrons. $$=2.457×10^{19}$$
