Problem 3 20pts Determine the equivalence current or voltage

Problem 3: (20pts) Determine the equivalence current, or voltage, or resistance between nodes a and b in each network shown below. (Show your work a. (10pts) 3i 2i

Solution

(a) In this figure, i_x and 2 i_x are in opposite directions

final resultant is -ix + 2ix + 3ix = 4ix

R = 2 ohms

(b) I = +10 - 2 - 3 = +5 sin 3t A
