A resistor obeys Ohm's law (\$\small V=I\cdot R\$); the current through it is equal to the voltage across it divided by the resistance (equivalently \$I=\frac{V}{R}\$).

What's wrong with my answer finding the resistance?
I think I found it:
The mistake happened in Step 3: it should be:
$$
-(-2) + V_{src} + 2\cdot I = 0 \\
2 -6 + 2\cdot I = 0\\
I = 2\mathrm{A}
$$
Then, step 4:
$$
1 - 2 - I_1 = 0 \\
I_1 = -1\,\mathr …

Trouble finding the R(equivalent) in this circuit
The equivalent resistance R2 for parallel resistors 24Ω and 12Ω is 8Ω (24x12/24+12).
The equivalent resistance R3 for resistors in series R2 and 22Ω is 30Ω (8+22). … The equivalent resistance R4 for parallel resistors R3 and 45Ω is 18Ω (30x45/30+45).
The equivalent resistance Rab for resistors in series R1 and 18Ω is 30Ω (12+18).
Why is the final answer 34Ω? …

Is my circuit analysis correct in this problem?
This is the problem:
My solution:
I'm new the delta-to-y and y-to-delta transformation, it is obvious we need to use them. I got the same answer but I'm a bit skeptical about my solution.
Is my …

What's wrong with my answer finding the resistance?
This is the question and the solution:
Here's my answer:
My answer was incorrect, though I believe my analysis was correct. Can anyone point my mistake? I hope it's not with the signs.

How do I find the resistance between three terminals?
I'm trying to self-study this problem and I found a bizarre problem with an unusual circuit.
I have never faced this in all the problems that I have solved. What do they mean by finding the equival …

Can't find the correct voltage and current source
What I tried to do:
The equivalent resistor R1 for the 12 and 4 ohm resistors is 3 (12x4/12+4).
The equivalent resistor R2 for the 4 and 12 ohm resistors is 3 (4x12/4+12). …
