Homework Help: Find current (in mA)

  1. Jul 14, 2010 #1
    1. The problem statement, all variables and given/known data

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

    V = 2.5V
    R = 1.6kΩ

    2. Relevant equations

    3. 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.

    Re: Units

    Convert Ampere to milliAmpere.

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