Homework Help: Superposition and electronic circuits

  1. Dec 10, 2007 #1
    1. The problem statement, all variables and given/known data
    Can someone please explain to me how to find the voltage across BD in the attached circuit. I can't do these examples. Please help.

    2. Relevant equations

    3. The attempt at a solution
    When I shorted one source I get the source current as 10.08mA and a voltage drop across the 200 ohm resistor of 2.02V.

    I think your drawing is missing the current source??? Be that as it may, REMEMBER: SHORT current sources and OPEN voltages sources. Do that, give us a complete drawing and show your work and we can help you if needed.

    Ok, assuming that the circuit is correct, V_BD= V acrosss 300ohms + 3.71V. You need to find that voltage by using KVL.

    Hope that helps.
