The Attempt at a Solution
I'm doing a practice problem and I can't seem to get the right answer.
I just want direction in the way to solve it, these are my "ideas" so far is to
Find Req, find source current, use current divider rule and find current in each branch. Then calculate the voltage at the points(I assume its just current*resistance of the resistor in front of the point?) I have no idea if this is the way I'm meant to solve it but I tried it anyways.
So left side total resistance is 650,
Right side is 1100,
top is 1000
all are in parallel? Or is 1000 in series with two parallel? I assumed in parallel in my calculations.
650ohm1100 ohm = 393.93 ohm
393.93 ohm1000 ohm=282.6 Req
50V/282.6 Req=0.1769 is
0.1796 mA*1000/2393.93 ohm = 0.073907 mA for current through the entire circuit excluding top
0.073907 mA * 1100ohm/1750 ohm=0.0464 current through left side
voltage at B = 0.0464*100ohm=4.64 V
The answers are meant to be
A=3.85 V
B=42.31 V
C=50 V
D=5 V
