Question

Hello, please can you explain the relationship between current, charge and coulomb, as well as the formula I=Q/t?This isn't an assignment question, so I'd be most grateful if you could really dig into it, however my understanding will be limited as I'm only of middle school age.

Answer 1

A charge is a property of any matter that makes the matter experience a force when it is placed in an electric field. Generally, 'Q' or 'q' is the symbol used to represent the charge.

Coulumb is the SI unit of the charge. And the symbol of the coulomb is C.

The current is the time rate of change of the charge. That is, the current is the flow of charges. That means, when the charge flows, there will be current. The current is represented by the symbol 'I'.

The SI unit of the current is ampere and the symbol of the ampere is 'A'.

Therefore the current is given by,

`I=(Q)/(t)`

Where Q is the charge and t is the time.
