Question

what is the electric unit of charge?how many electrons constitute a charge equal to 1C​

Answer 1

Electric charge has the dimension electric current time. The SI derived unit of electric charge is the coulomb, which is defined as an ampere second.Total charge required 1Coulomb. the number of electrons constituting one coulomb of charge. We know that the a electron have charge of 1.6 × 10−19 C. then 1 coulomb of charge contans = 1/(1.6*10^-19)=6.25*10^18 electrons.

Answer 2

➠ $\huge\boxed{Coulomb}$

The SI derived unit of electric charge is the coulomb, which is defined as an ampere second.

★ We know that the a electron have charge of

1.6 × 10-¹⁹C

then 1 coulomb of charge contans

= 1/(1.6×10-¹⁹)

=6.25×10¹⁸ electrons.
