Question

A physics grad student has a machine that measures how

many electrons are whizzing through a ring. If she measures 2
Coulombs of charge flowing through the ring every second,
what is the current passing through the ring?
1 = _A

Answer 1

2A

Step-by-step explanation:

Given parameter:

Quantity of charge = 2C

Time taken = 1s

Unknown:

The current passing through the ring = ?

Solution:

Current can also be defined as the quantity of charge that passes through a conductor per unit of time:

I =
`(q)/(t)`

So;

I =
`(2)/(1)` = 2A
