1.	The current flowing through a wire is 1 A. If the charge of an electron is 1.6 x 10-19 C, then the number of electrons flowing through any section of the wire per second is(A) 0.625 x 1013(B) 6.25 x 1018(C) 1.6 x 10-19(D) 1.6 x 1019
Answer» The correct option is (B) Given that Charge (Q) = 1 C Electron (e) = 1.6 x 10^-19 Number of electron (n) = ? Q = ne 1 C = n x 1.6 x 10^-19 C n = 1/(1.6 x 10^-19) n = 6.25 x 10¹⁸ electron

Answer»

The correct option is (B)

Given that

Charge (Q) = 1 C

Electron (e) = 1.6 x 10^-19

Number of electron (n) = ?

Q = ne

1 C = n x 1.6 x 10^-19 C

n = 1/(1.6 x 10^-19)

n = 6.25 x 10¹⁸ electron
