Question

Calculate the number of electrons in 4.8C of electric charge

Answer 1

1C consists of 6.25×10^18 electrons.

So 4.8 C consists of 4.8×6.25×10^18 electrons.

That is equal to 30 ×10^18 electrons.

Answer 2

The number of electrons are $3\times 10^{19}\ electrons$.

Explanation:

It is given that,

Charge, q = 4.8 C

To find,

The number of electrons

Solution,

We need to find the number electrons. We know that charge is quantised. According to the quantisation of electric charge,

q = ne

n is the number of electrons

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

$n=\dfrac{4.8}{1.6\times 10^{-19}}$

$n=3\times 10^{19}\ electrons$

So, the number of electrons are $3\times 10^{19}\ electrons$.
