Need help working this out

[Ashton Woodward]

I need help working this out. Its something for school and im stuck on it. https://gyazo.com/450f1fd62d4356091a906f159e968b70 it says that i have to use one of kirchoff's laws to determine the current in various parts of network having four nodes and the dissipated in a load resistor containing two voltage sources. if you could can you please set it out like this. https://gyazo.com/6e05f1178bac70817de68213a3ae9932 this is one of the other questions that i have answered.
the reason im asking for help on here is because im new to course and the teaching doesnt explain things clearly. i really need help and would appreciate it someone would.
Thanks

We will not answer the question for you - we'll help you find the answer yourself:

From Kirchhoff's first law: I3=I1+I2
From Ohm's law: V(R)= I*R
From Kirchhofff's second law: 10V = I1*R1+I3*R3 and similarly for the second voltage source.

This leaves you with three equations (one from the 1st law, two from the second law) and three unknows (I1, I2, I3). This set of equations you should be able to solve.

Hi Ashton,
If you started the course a little late or having problems understanding it, I suggest you do some home learning by yourself.
This can sometimes make it all drop into place (for me at least).
You can start with something like this tutorial.
There are many many more to view too.
