Question

a) Define the term “electric current” in terms of electron and charge on an electron as a physical and mathematical quantity.

Answer 1

Answer:

Electric current is the charge flowing through a certain area per unit time.

Explanation:

Say n electrons are flowing through a particular surface area in time t. Then,

Total charge flowing through that area is q=ne, where e is the fundamental unit of charge with a magnitude of 1.6*(10)^(-19)C.

So, electric current through that surface are is,

i= q/t= (ne)/t

Answer 2

Answer:

Electric current can be defined as the flow of charge per unit time. That is

Explanation:

I = Q / t

Here, I is denoted by electric current

Q is denoted by flow of charge

t is denoted by time taken

It can also be written as :

I = ne / t ( because Q = ne)
