The circuit in the figure below has been connected for a long time. Let R1 = 7.00 ? and R2 = 4.40 ?.
Solution
VA - VD = I2 * 4.4 ohms = [10 / 4.4 + 1] * 4.4 = 8.15 V
VC - VD = I3 * 2 ohms = [10 / 2 + 7] * 2 = 2.22 V
VA - VC = 8.15 - 2.22 = 5.93 V
-------------------------------------------------
R = [(1 / 1 + 7) + (1 / 2 + 4.4)]-1
= 3.56 ohm
t = - RC ln[1/4] = 3.56 * 1 * 10-6 * ln 4
= 4.93 mus
