Question

a current of 3.6ma is flowing through the element of a vaccum tube. how many electrons are flowing per sec through the element.​

Answer 1

Answer:

Current, I = q/t

q =ne

Where n is the number of electrons and e is the charge of electron which is 1.6×10^-19C.

q is the charge, t is the time.

Given---> I=3.6mA, t=1s

So, 3.6×10^-3 = ne

n = 3.6×10^-3 ÷ 1.6×10^-19

n = 2.25×10^16 electrons.

Hope the answer is clear for you.
