Question

If the charge on an electron is 1.6x10-19 coulombs,how many electrons should pass through a conductor in 1 seconds to constitute 1 ampere current?

Answer 1

$\huge\mathbb{Hello}$
$<b><i><u>$
Given that ««««

Charge (Q) = 1 C
Electron (e) = 1.6× 10^-19
Number of electron (n)=?

[Solution]

Q= ne
1 C = n × 1.6×10^-19 C
n = 1/(1.6×10^-19)
✔️n = 6.25 × 10^18 electron

Answer 2

Answer:

hola mate,

if charge on electron [e]=1.6×10^-19 c

time t= 1 sec

current =1 ampere

I = q/t

so q=It

and we known that

q = ne

It= ne

1A×1sec= n ×1.6×10^-19

n= 1/1.6×10^-19

n = 6.25 ×10^18

hope it helps.
