The number of electrons in one coulomb of electric charge is :
- A 6.25 \(\times 10^{-18}\)
- B 6.25 \(\times 10^{18}\)
- C 1.6 \(\times 10^{-19}\)
- D 1.6 \(\times 10^{19}\)
Answer & Solution
Correct Answer
(B) 6.25 \(\times 10^{18}\)
Step-by-step Solution
Detailed explanation
\( N = \frac{Q}{e} \) \( N = \frac{1 \, C}{1.6 \times 10^{-19} \, C/electron} \) \( N = 6.25 \times 10^{18} \text{ electrons} \)
