    I used superposition to turn off each individual sources and build two seperate circuits, and seperate the resistors and then add them together and multiply by the current for the total V. then used voltage divider law and add up but keep getting wrong answers.

    Does anyone also have any good links to studying and learning voltage division, current division, short circuit, open circuit voltage, thevenins, nortons and superposition ?

    Also have another problem with switches. for a question i need to calculate the net resistance of a circuit for when a switch is on and again once it is off. i'm guessing if the switch is on it's just a normal circuit, but what happens when it's off?
