AI Thread Summary
The discussion revolves around solving a circuit problem using Kirchhoff's laws, specifically focusing on the magnitude and direction of current in a resistor circuit. The original poster is confused about their calculated current value of 8.2 ohms, which is incorrect as current should be measured in amperes. Participants suggest applying Kirchhoff's laws correctly and emphasize the importance of clearly defining the direction of currents entering and leaving junctions. The need for a clearer circuit diagram is also highlighted to facilitate better understanding. Overall, the conversation aims to clarify the application of Kirchhoff's laws to determine accurate current values in the circuit.

this is a rough diagram of the picture, please note the direction of the current. that is what is throwing me off right now. The answer I get for I3 is 8.2 ohms and that seems a bit unrealistic to me.
the question is
a) what is the magnitude of the current in each resistor
b) what are the directions of the current in each resistor

thanks in advance!

Well, apart from the picture being impossible to interpret, the answer simply cannot be 8.2 ohm as currents are measured in ampere.

Otherwise it should be a simple matter of applying Kirchoff's laws. Assume a current for each resistor and see where it takes you. If you write down how you arrive at your result, it will be easier to see if and where you go wrong.

I meant Amps, sorry. Even though, it seems like a very large number. Also, I uploaded a picture of the circuit so it can be interpreted.
 
So, what relations have you obtained from Kirchoff's laws?
 
Just FYI, I deleted several posts to clean the thread up.

This is what I have so far

You may want to reconsider your application of the current law. Which currents go into the point and which go out?
