Question

an electric current of 1.6 A is passed in a conductor for 10 sec. the the number of electrons that moved through the conductor in a given time is:
a) 16 C
b) 6.25×10^(18) electrons
c)10^(20) electrons
d)None​

Answer 1

Answer:

Ans- (C)

${10}^{20 \:} electrons$

Explanation:

we have

$electric \: current = \frac{ne}{t}$

or, 1.6 =

$\frac{n \times 1.6 \times {10}^{ - 19} }{10}$

$or \: n = \frac{1.6 \times 10}{1.6 \times {10}^{ - 19} }$

$or \: n = {10}^{20} electrons.$
