Question

Potential difference of 10v is applied across a conductor of 1000 ohm.the number of electrons flowing through the conductor in 300 s is

Answer 1

Hi bro answer is noob

Answer 2

Explanation :

It is given that,

Potential difference, V = 10 V

Resistance, $R=1000\ \Omega$

Time taken, t = 300 s

The relation between number of electrons and electric charge is:

$q=ne$

$n=\dfrac{q}{e}$

where,

n is the number of electrons

q is the electric charge,  $q=I\times t$

also, $I=\dfrac{V}{R}$

So,

$n=\dfrac{Vt}{Re}$

$n=\dfrac{10\ V\times 300\ s}{1000\ \Omega\times1.6\times 10^{-19}\ C}$

$n=1.875\times 10^{-19}$

Hence, this is the required solution.
