Thanks for pointing out my mistake. So when I try to simplify (2+j) + (-4j/(2-2j)), I am getting a fraction. How do I simplify this correctly? and what happens if there is a j^2.
Homework Statement
If R1 = 2 Ω, X1 = 1 Ω, R2 = 2 Ω, and X2 = -2 Ω , the equivalent impedance Zeq (in ohms) at terminals a and b is:
(the circuit diagram is attached to this post)
a. 3 + j 0
b. 3 + j 2
c. 3 - j 2
d. 0 - j 2
e. 0 + j 2
The answer is a. I have no idea how to...
Homework Statement
I have attached the circuit diagram to this thread.
V=12V, R1=2kΩ, R2=2.7kΩ, R3=1kΩ, R4=5.1kΩ.
Find I1, I2, I3, I4, I5, I6. Find VA, VB, VC, VD.
I just don't know how to apply kirchhoffs law to find the current and the voltage. I don't expect to have all answered. If...
