Question

6 into 10 ki power 17 electron cross through an area per minute what is the electric current​

Answer 1

Answer :-

♦ As it's Given :-

• No of electron pases per minute

= $6 \times 10^{17}$

♦ So as we know that

Electric current = Charge per second

$I = \dfrac{Q}{t}$

♦Now as charge on one electron

$= -1.6 \times 10^{-19}$

So

$Q = |(6 \times 10^{17} ) \times (-1.6 \times 10^{-19})|$

$Q = |-(6\times 1.6) \times 10^{-2}|$

$Q = | - 9.6 \times 10^{-2}|$

$Q = 9.6 \times 10^{-2}$

**Note As charge is considered as positive , hence we took mod of charge.

♦ Now As time = 1 min = 60 sec

• Then

$I = \dfrac{Q}{t}$

$\implies I = \dfrac{9.6 \times 10^{-2}}{60}$

$\implies I = \dfrac{1.6\times10^{-2}}{10}$

$\implies I = 1.6 \times 10^{-3}$

So Electric current = $\bold{ 1.6 \times 10^{-3}}$
