If a current of 1.5 ampere flows through a metallic wire for 3 hours, then how many electrons would flow through the wire?

$2.25 \times 10^{22}electrons$

$1.13 \times 10^{23}electrons$

$1.01 \times 10^{23}electrons$

$4.5 \times 10^{23}electrons$

Answer

$1.01 \times 10^{23}electrons$

Explanation

$Q = I \times t = 1.5 \times 3 \times 60 \times 60 = 16200C$

Charge on 1 electron $= 1.602 \times 10^{- 19}C$

16200 C charges is on $\frac{1 \times 16200}{1.602 \times 10^{- 19}}electrons$

$= 1.01 \times 10^{23}$ Electrons
