1. The problem statement, all variables and given/known data Find Vout at t=0.782s (I already found Vout at t=0 s. It is 0 V.) 2. Relevant equations V=IR 3. The attempt at a solution First I found Vs = 9*sin(14*0.782)=-8.989817V (with t in radians) Since Rpi is in parallel with the Vs, its voltage Vpi also equals to -8.98917 V. Since the dependent source is I=10^-3*Vpi= -8.989817E-3 A, it is the same current traveling through the 1000 ohms resistor in the right loop. Using the equation: Vout=IR=8.989817E-3A*1000ohms=8.990V (Current is positive in this case since the current direction is opposite of the passive configuration. That is, it is going from - to + instead of + to -.) Apparently, my answer is wrong. Would any one please help me to see where I am doing wrong here? (I wonder how does the wire connect the two loops affect the situation. Is it possible that the R in Vout=IR is not 1000, but 1050 (50 ohms resistor in the left loop since both resistors might be in series?) Many thanks in advance!
