Engineering Finding current in a resistor (in a big circuit)

AI Thread Summary
To find the current in the 50-ohm resistor, node analysis using Kirchhoff's Current Law (KCL) is recommended. KCL states that the total current entering a node equals the total current leaving it. The user applied node analysis and calculated the current to be approximately 0.15A. Confirmation of this result is sought from others in the discussion. Utilizing Thevenin and Norton equivalents may also be beneficial for solving similar circuit problems.

hi,

can anyone help me with this problem? i need to try find the current in the
50ohm resistor marked with an 'x'.

any help would be greatly appreciated!

What are the relevant equations for finding that current?
 
i think it is supposed to be done my using norton and thevenin equivelent circuits or possibly node analysis? and then applying ohms law...

i do appreciate any help at all

thanks!
 
Yes, I would use node analysis in the form of Kirchoff's Current Law to solve this problem. What can you tell us about how to apply the KCL? We do not give out answers here on the PF, but we can help to point you in the right direction.
 
main point with KCL is that current into a node equals current out.I had another go at the problem with node analysis, and i got 0.15A approx, i think its right, can any1 confirm this
