The problem is shown below: (I am only asking about part b) ^Above is the problem. Below is the solution to part b. They have claimed that we can set potential at C = D = u(t), and A=B=0. Why is this claim true? What I realize: By applying Kirchoff's across ACDB, Voltage across C1 = Voltage...

1. Homework Statement the problem is my answer for question (a) is not the same as the answer provided by the question, i get 2.81 - j4.49 Ω while the answer demands 2.81 + j4.49 Ω Homework Equations simplifying the circuit, details can be seen below The Attempt at a Solution...

Homework Statement Find currents I1 and I2 in the following circuit: Homework Equations I know I have to use Kirchoff's loop rule but I am not sure of the current going through the 5 ohm and 8 ohm resistors, is it just I1 and I2 respectively? Also do I incorporate the large loop at the...

Homework Statement Homework Equations Req = [ ( 1 / R1) + ( 1 / R2) +. ...]^-1 (Parallel) Req = R1 + R2 +. . . (Series ) The Attempt at a Solution I tried to simplify the circuit by spreading it out but I guess something is wrong with my simplification since I can't arrive at the correct...

Homework Statement A combination circuit powered by a 6.0 V battery is shown. What is the total current through this circuit? I don't know how to determine where the signs go, for example if the right side of a resistor is positive or the left side is positive Homework Equations What is the...

Homework Statement uploaded is the circuit with resistors technically in series. R1 had a measured value of 160 ohms (from A to B) 0.0617 Amps R2 had a measured value of 387 ohms (from B to C) 0.025 amps from A to C the resistance measured is 243.9 ohms 0.041 amps this means that there is a...

I would like to what is the best way to analyze complex circuit with resistors in series and parallel. I have attached a sample circuit. You can also show it to me with other circuits. Thanks

I know how to detect when resistors are arranged in parallel or series arrangement and I can also find their equivalent resistance in simple circuits or when resistances are connected in form of triangle but what happens when the arrangement is complex like this : Which resistors are...

I have the diagram on the right, I've set up a few equations to solve... My calculator tell me mathematical error. can someone point out the error? thanks. http://img21.imageshack.us/img21/5395/imgyqc.jpg

****WARNING-THIS IS NOT A HOMEWORK-WARNING**** Hello dear Physics Forums users, I have no idea about how to find the potential difference between two points in a complex circuit. I m not even sure if I really know how to find it in a basic circuit. Please help me and enlighten me with your...

Homework Statement Refer Attachment Homework Equations The Attempt at a Solution I have drawn the current direction in green. Are there any rules regarding the direction of the current? I am at a bit of a loss regarding the horizontal current through the middle. The best I could...

Homework Statement R=resistor determine the voltage across and the current through each resistor for the circuit. The Attempt at a Solution 1&2=parallel 1/50+1/25=3/50 --> 50/3=16.7 ohms 3&4=parallel 1/10+1/10=1/5 --> 5 ohms 5&6=series 5+10=15 ohms total resistance=36.7...
