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?

Q1) For the current to voltage amplifier question, it seems like there may be some confusion about the values given. It is not clear what the 5(i1) term represents. Can you provide more information or clarify the question?

2) To find the Thevenin equivalent resistance, you can use the formula Rth = Vth/Isc, where Vth is the Thevenin voltage and Isc is the short circuit current. To find Vth, you can use the voltage division formula with the 7V source and the 10 ohm resistor. To find Isc, you can short the terminals and find the current flowing through the 10 ohm resistor.

3) To find the Norton equivalent current, you can use the formula In = Isc, where Isc is the short circuit current found in part 2. The 1 ohm resistor will affect the current by reducing it, since it is in series with the 10 ohm resistor.
