Question

A conductor carries a current of 0.2A.Find the amount of the charge that will pass through the cross- section of the conductor in 30sec.How many electrons will flow in this time interval? ​

Answer 1

Explanation:

so, 3. 75×1019 electrons will flow through the cross section of the conductor.

Answer 2

$\huge\bigstar\underline\mathfrak{Answer:-}$

Current, I = $\frac{Q}{T}$

0.2 A = $\frac{Q}{30}$

0.2 × 30 = Q

Q = 6

_______________

We know,

Q = ne

6 = n× 16 × ${10}^{-19}$

$n = \frac{6}{1.6 \times {10}^{ - 19} }$

$n = 3.75 \times {10}^{ - 19} electron$
