Homework Statement
Find all resistance, voltage, current, and power values for the circuit.
Homework Equations
I = V/R V = IR R = V/I
Voltage Divider Rule
Current Divider Rule
The Attempt at a Solution
I simplified the circuit down to equivalent values. Sorry for the poor image of the circuit.
I turned the R1 and R2 parallel combo into Req1, = 60 ohms.
Then added the series combo of R6 + R7 in the middle, Req2 = 120 ohms.
The parallel combo of R4 and R5 at the top, Req3 = 160 ohms.
Added the series combo of R3 + Req3, Req4 = 240 ohms.
Solved the parallel combo of Req4 and Req2, Req5 = 80 ohms.
Then I'm left with 3 resistors in series, Req 1 + Req5 + R8, RT= 220 ohms.
I found total current, IT= VT/RT, 660 V/220 ohms, = 3 A
Found total power, PT= IT*VT, 3A*660V = 1980 A
Then I tried to find the current of R1 by using the current divider rule. I came out with 2 A.Now, I am wondering if I did it right and how do I tackle those resistors in the middle, do I just use voltage divers/current dividers?
If anyone can check if I did it right or offer advice, it would be much appreciated. Thanks.
