Basic Electrical Mcqs

Q.  If 1 A current flows in a circuit, the number of electrons flowing through this circuit is

a. 0.625 × 10¹⁹
b. 1.6 × 10¹⁹
c. 1.6 × 10⁻¹⁹
d. 0.625 × 10⁻¹⁹


ANSWER: See Answer
 
The charge of one electron is 1.6 × 10 – 19 coulomb. Again 1 A current means transferring of 1 coulomb charge per one second.
