Homework Help: Current, Voltage Really Easy Question

  1. Jan 24, 2007 #1
    1. The problem statement, all variables and given/known data
    In the circuit shown, the battery provides a current I = 0.3 A to the resistor.

    The battery is 12 V, and it states a current of .3A

    a. How much current is returned by the resistor to the negative terminal of the battery?
    b. How much current flows inside the battery from the negative to the positive terminal?

    2. Relevant equations
    Ohm's Law I = VR

    3. The attempt at a solution

    What I don't get is that all three variables are given. 12v/50A = .3ohms, but that just verifies the given. How would I determine the current returned to the resistor?

    Since both elements are is series, they are crossed by the same current.

    Ok, that makes sense because that wasn't making sense until then.

    what do you mean by saying they are in series? what is in series? and what gets crossed?
