Calculate the current between point A and B

Click For Summary
The discussion revolves around calculating the current between points A and B in a circuit with given resistances and a voltage of 12V. The total resistance is determined to be 4 Ohms, leading to a total current of 3 A. Participants clarify the use of parallel and series resistor formulas, emphasizing the need to understand the configuration of the circuit. The voltage drop across resistors in parallel is discussed, with the conclusion that the current flows from A to B, with specific current values through individual resistors calculated. The conversation highlights the importance of accurately applying circuit laws to derive the correct current and voltage values.

From the direction of current through R1 and R3 and the difference in the currents.

Double check all results by considering R2 & R4 as well.

Yeah that makes a lot of sense! The direction of the current must be from A to B then.

Thanks.

@Qwertywerty ,

Your suggestions were fine, but I felt that meguco0314 would benefit from using basics rather than using a proportionality argument for finding individual currents.

Yes thank you so much! Your help was awesome! I learned more than a thing or two from this, and I hope others will benefit from this thread as well. :)
