Hey guys, I hope you're all well and Happy New Year.
I have some exams coming up, but I am having some trouble commanding KVL and KCL effectively. I understand how to use them when there are two loops and two sources, but not so confident when it comes to three sources... I can't get my head around how KCL operates at a node when theres a voltage supply just before it... Could somebody please help me derive the correct equations so I can find the voltage and current through each resistor? I appreciate any help you guys can give me.
in circuit a, R1=R2=R4= 1 kΩ, R3 = 2 kΩ
in circuit b, R1=R2=R3=R4 = 1 kΩ
