Homework Statement



When a question asks you to find current (in mA) what does it mean?

V = 2.5V
R = 1.6kΩ

Homework Equations





The Attempt at a Solution



What I did was

2.5V = I(1600 Ω)
I = 0.0015625 A

Is that correct?

The calculation is correct, but it is not in the requested units.
 


How do i get the correct units?
 


Convert Ampere to milliAmpere.

It is just like converting metre to millimetre or kilometre to metre.
