How many electrons are flowing per second past a point in a circuit in which there is a current of 5 amp ?

Answer 1

Explanation:

ANSWER

Given that,

Current i=5A

Time t=1s

Charge e=1.6×10

−19

C

We know that,

Q=it

ne=it

n=

e

it

n=

1.6×10

−19

5×1

n=3.125×10

19

n=3125×10

16

Hence, the number of electrons is 3125×10

16
