Question

How many electrons are transported by a current of 1.2 A flowing for 16 minutes and 40sec

a) 75x1020 b) 50x1015 c) 25x1010 d) 75x1021​

Answer 1

Answer:

A current of 1A flows in a wire carried

As other answers have pointed out, 1A passing for 1s is 1 Coulomb of charge.

How many electrons in a Coulomb? Your question says “the charge of an electron is -1.6 x 10^(-19) C.” So the number of electrons in a Coulomb is the reciprocal of that number. So from your information the answer is 1/1.6 x 10^(-19) =6.25x 10^18 electrons.

According to Wikipedia: “roughly 6.241509×10^18 electrons”.

As you say, it is very simple. If you didn’t understand how to answer it shows you missed the fundmental facts about Coulombs. If you still don’t ‘get it’, ask for help. That’s what teachers are for!

Answer 2

Answer:

1200

Explanation:

current= charge,× time

charge =current× time

1.2 = ( 16*60+40)

1.2=(960+40=1000)

1.2*1000= 1200
