Holy current, how do you find the the current at each ammeter??

Homework Statement


Find the current at each ammeter.

SYSTEM.png

My solution
Someone told me to use
[tex]\sum[/tex]E-[tex]\sum[/tex]IR=0
to solve the system but they weren't sure.

But I cannot find anything about this on the internet and I'm freaking out!

Use Kirchhoff's junction and loop laws.
The sum of the voltage differences around any closed loop equals to 0.
The current entering a junction equals the current exiting a junction.
 
The person that told you to use:

[tex]\sum{E}-\sum{IR} = 0[/tex] is partially correct. You need to use that (it's called Kirchhoff's Loop Rule).

You also need to use Kirchhoff's junction rule [tex]\sum{i_{in}} = \sum{i_{out}}[/tex].
 
thanks mates this helped a lot :approve:
