Question

If 10^6 electrons per second are flowing through an area of cross section 10^-4m^2 then the current will be?​

Answer 1

Answer:

The current will be $1.6\times10^{-13}\ A$

(2) is correct option.

Explanation:

Given that,

Area $A=10^{-4}\ m^2$

If $10^6$ electrons per second ,

We need to calculate the current

Using formula of current

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

Where, I = current

Q = charge

t = time

Put the value into the formula

$I=1.6\times10^{-19}\times10^{6}$

$I=1.6\times10^{-13}\ A$

Hence, The current will be $1.6\times10^{-13}\ A$.
