Your name (printed ):_____________________________________________________ Problem 1 2 - + 2 18 5 Use the “node voltage ” method to solve for: Vae , Vbe and Vce . Do not simplify the circuit by combining resistors or substituting equivalent configurations. i 15 Volts Controlled current source: i = 0.2 Amperes/Volt x Vbe Hint: 1 Ampere/Volt is the same as (i.e. is equal to): 1/(1 Ohm) i.e. 1 Ampere/Volt x 1 Ohm = node e node b node a node c

Problem 1 Solution Equation (a): Va = 15 Volts Equation (b): (Vb - Va)/18 + Vb /2 + (Vb- Vc)/2 = 0 Equation (c): (Vc - Vb)/2 + Vc /5 - i = 0 Equation (d): i= 0.2 Amperes/Volt x Vb Algebra: multiply both sides of equation (b) by 18 ; multiply both sides of equations (c) and (d) by 10 ; Va = 15 Volts
Your name (printed ):_____________________________________________________ Problem 2 2 15 Volts - + 2 18 5 Controlled current source: i = 0.2 Amperes/Volt x Vbe Use the “mesh current ” method to solve for: i1 , i2 , i3 and i4 . Do not simplify the circuit by combining resistors or substituting equivalent configurations.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
