MCQ
Number of electrons in 1 Coulomb charge is _________?
- A6.25 × 1021
- B6.25 × 1020
- C6.25 × 1025
- D6.25 × 1023
Explanation:
Electron has the charge of 1.602 × 10-19 Coulomb. So, the number of electrons in 1 Coulomb of charge is $\frac{1}{1.602\times10^{-19}}=6.25\times10^{21}$
This huge number of electrons can be accumulated to form 1C of charge.
Thus, we can conclude that we need Avogadro’s number of electrons (approximately) to get 100C charges.
