Question

how many electrons constitute 1 ampere current​

Answer 1

Answer:

one electron constitute 6.25×10^-18 ampere of current

Answer 2

Answer:

6.25×10¹⁸ electrons constitute 1 Ampere of current.

Explanation:

When a 1-coulomb charge flows through a conductor in 1 second then the current through the conductor is 1 Ampere.

Also, the current through a conductor is given as,

$I=\frac{Q}{t}$          (1)

Where,

I=current flowing through the conductor

Q=charge on the conductor

t=time during which the charge flows

$Q=ne$        (2)

n=number of electrons on a conductor

e=charge on an electron=1.6×10⁻¹⁹C

By placing the required values in equation (1) we get;

$I=\frac{ne}{t}$

$1A=\frac{n\times 1.6\times 10^-^1^9}{1 sec}$

$n=\frac{1\times 1}{1.6\times 10^-^1^9} =0.625\times 10^1^9=6.25\times 10^1^8$

Hence, 6.25×10¹⁸ electrons constitute 1 Ampere of current.
