- Find the values for R1 and G (gain) in following circuit.

Hint: start by writing a KCL at bottom node

- Relevant Equations
- KCL, KVL, Ohm's Law

I've gotten to the point where I've hit a roadblock and am not sure what step to take next. I started by using KCL on the bottom node as suggested by the problem, then used KVL on the left mesh, but I still have ##i_{v_s}## which I'm not sure what to equate it to, so that I can pull it out of the equations. I can't say that Gv##_2## = 20 V b/c Gv##_2## is a current value, right?

I'm also wondering if this problem is solvable as is b/c it's actually a stripped down version of a problem in our textbook: Introduction to Electric Circuits 9th Edition. James A. Svoboda. Richard C. Dorf.

The problem in the book gives additional information:

The voltage source in the circuit shown in Figure P 3.2-25 supplies 2 W of power. The value of the voltage across the 25-##\Omega## resistor is v##_2## = V. Determinethe values of the resistance R##_1## and of the gain G of the VCCS.
