    It's problem number 4 of the attached PDA file...please help. I understand basic circuits: how to find current, voltage, resistance, etc., but I don't know how to do it with the open switch, and how it affects the overall problem and why. Thanks for your help!

    How much current can pass through an open switch? Does that change when the switch gets closed?
