Calculate the number of electrons constituting one coulomb of charge: - Sri Chaitanya Infinity Learn Best Online Courses for NCERT Solutions, CBSE, ICSE, JEE, NEET, Olympiad and Class 6 to 12

Concept: As we know charge on 1 electron is

e = 1.602 \times 10^{- 19} c

Now for 1 C of charge number of electrons required is

1 = n \times e n = \frac{1}{1.602 \times 10^{- 19} c}

So, number of electrons is

6.25 \times 10^{18}

Hence, option 1 is correct.
