A few quick circuit questions, amps, norton's equivalent, etc

  1. Apr 19, 2010 #1
    1. The problem statement, all variables and given/known data

    Problems below in attached files.


    2. Relevant equations

    http://en.wikipedia.org/wiki/Norton's_theorem
    http://en.wikipedia.org/wiki/Maximum_power_theorem

    3. The attempt at a solution


    Q1) current to voltage amp question

    Attempt:
    if i1 is 2mA. Then 5(i1)=.01, therefore using voltage division Vo is equal to .005 volts? I thought this was an amplifier?

    2) Max Power Question

    How do i find the Thevin equivalent resistance? Isn't it the resistance in the circuit "looking back" from the terminals and shorting the voltage src? Then is 177.77ohm correct?


    Q3) Attempt:
    To get a Norton equivalent i must short the terminals and see what current goes through them. How do I calculate this current? Is it 7amps? What affect does the 1ohm resistor have?
