电路学第一次小考(Chap1-Chap4)
9:10-10:00, 10/22/2014
1. Use Superposition to find v_1 in fig. 1(20 points). You can only get 10
points, if you find the correct answer without superposition.


2. a. The net work in Fig. 2(a) acts at its terminals like an ideal voltage
source of value v_oc in series with a resistor having resistance R_t as
in Fig. 2(b). Please find v_oc and R_t (20 points, 10 points for each).
b. The net work in Fig. 2(a) acts at its terminals like an ideal current
source of value i_sc in parallel with a resistor having resistance R_t as
in Fig. 2(c). Please find i_sc and R_t (20 points, 10 points for each).


3. Find the potentials (node voltage) of points a and b in Fig. 3
(20 points, 10 points for each)


4. Find the i_a and i_b in Fig. 4 (20 points, 10 points for each)
