Calculate voltage

  1. Oct 23, 2011 #1
    I'm trying to determine the voltages and currents at points A, B and C of the attached drawing. I tried it by using the superposition theorm. Only this doesn't work with the voltage source, because the current can't "run" through the circuit, because the currentsources are than deleted, and there is no closed circuit.
    My question is: what is the right way to calculate the voltages and current at the 3 points. And what are voltages and currents at the 3 points?

    Thanks for your help!

    Welcome to Physics Forums.

    To start, can you say what the voltage at B is, as well as the currents at A and C?

    For the rest, try using Kirchhoff's Current Law and Voltage Law (KCL and KVL) for the circuit.
