SOLUTION ENGG1203– Midterm University Number: 2. Find the current i in the following circuit. 10Ω i + - 5V 10Ω 1 . 5A A. - 2A B. - 1A C. - 0 . 5A D. 1A E. This circuit is unstable and we cannot determine i . C 3. What is the gain of the following circuit relating V out to V in ? - + 2 R 2 R V out R 2 R 2 R V in A. V out = - 1 4 V in B. V out = - 1 3 V in C. V out = 4 V in D. V out = 3 V in E. V out = V in D 4. Which of the following is equivalent to ( a b ) c ? E Page 2 of 9
SOLUTION ENGG1203– Midterm University Number: 5. For the circuit below, A has resistance 5Ω, B has resistance 10Ω, and C has resistance 15Ω. Assume the current going through a resistor with resistance R is i , then power dissipated in the resistor is P = i 2 R . Arrange the power dissipated in these three resistors in descending order. 0 . 5A A B C A. A > B > C B. B > A > C C. A > C > B D. C > B > A E. C > A > B A

### 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.
