Answer: D. 14. Driving function is __________ produced by ______ because it represents an input that causes a circuit ______.
14. Driving function is __________ produced by ______ because it represents an input that causes a circuit ______. A. voltage…source…output. B.current …source…output. C. voltage or current…ideal source…response. D. voltage…ideal source…output E. current …ideal source…output
Solution: Driving function is voltage or current produced by ideal source because it represents an input that causes a circuit response. Answer: C.
A.1V B. – 1V C. 6V D. 5V E. – 5V
Solution: Equivalent circuit is
By KVL: 10 + 6 + v0 – 15 = 0; v0 = –1V Answer: B. 16. Define Thevenin voltage for the circuit in Fig.9. A.9V B. 8V C. 6V D. 5V E. 3V
Fig. 9 Solution:
Equivalent voltage source and resistors in series will be 3*2=6 and 4+2+3=9kΩ
Answer: C.
17. Equivalent resistance of parallel arrangement is equal to 6 Ω. Two resistors are connected in a parallel, one of them is 10 Ω. What is the second one? A.15 Ω; B.20 Ω C. 10 Ω D. 12 Ω E. 8 Ω
Solution: REQ for two parallel branches is Answer: A. 18. Find the correct formula for p. p = A. vi B. dw/dq C.dq/dt D. dq/dv E. di/dt Solution: p=dw/dt=vi.

15. Define Vo for the circuit to the right.
Equivalent current source will be 15/3*103=5mA
Equivalent current source and resistors in parallel will be 5–2=3mA and 6*3/9=2kΩ
. We know that REQ=6W and one of the resistors equals 10W. Let the second one will be XW. Substituting these values gives equation 
. Solving for X gives us X=15W.
