Prob 9-11a,b Fig 9-85  a. Find the Thevenin equivalent circuit external to RL b. Use the equivalent circuit to determine Vab when RL = 20 ohms and RL = 50 ohms a. Remove RL and replace first with a voltmeter and then with an ohmmeter. By inspection, with RL removed the 0.2 A current source current will all go through R1 creating  a voltage across R1 of 0.2*16 = 3.2 V. That voltage is in series with E therefore Vab = 3.2 + 2.4 =

Unformatted text preview: 5.6 V = Vth When the ohmmeter is applied the E must be shorted and the 0.2 A source must be opened. The ohmmeter will then read 16 Ω = Rth. b. For RL = 20 ohms use V div Vab = 5.6*20/(16+20)= 5.6*20/36 = 3.11 V c. For RL = 50 ohms use V div Vab = 5.6*50/(16+50)= 5.6*50/66 = 4.24 V...

### 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.
