Homework Help: Potential Difference Va-Vb

  1. Mar 31, 2013 #1
    1. If the current in the 4.0 ohm resistor is 1.4A. What is the magnitude of the potential difference. Va-Vb?

    2. V=IR, 1/Req=1/r1 +1/r2 ...

    3. Va-Vb= 48V

    I was stuck on beginning of the question. I knew how to start if the voltage is given but now asking me to find the potential difference and make me headache. I'm a beginner on the electrical course.

    Potential difference and voltage are two names for the same thing.
