KCL = Kirchoff's Current Law
The sum of the currents entering a node = the sum of the currents leaving.
This is true for every node in the circuit.
So you will obtain an equation connecting currents for each and every node.
How many equations will that yield in this case?
Note also that KCL has no voltages in it.
KVL = Kirchoff's Voltage Law
The sum of the EMF voltages around any closed loop = The sum of the IR voltage drops in that loop.
You can obtain an equation for each and every loop in the circuit
Note that KVL conains both voltages and currents
How many equations are therefore in your circuit?
These are the basic forms of Kirchoff's laws.
Others here will cut corners and combine these with other ideas to form what are known as the mesh equations which also contain both voltage and current.
These are short cuts that are best studied once the long slog method is fully understood.
Here is a start on your circuit.
I have labelled the nodes A and B and shown the currents for Node A
Can you do the same for NodeB?View attachment 83279
I am working through this in excruciating detail with you because I think you teaching material is too condensed and that you have either not seen or the basics.Would node B for the left loop 1 be i3 + i1 , loop 2 right side i3 + i2?
No.The way i see it as 17v goes into R1 as a + current then goes down to R2 am i correct in thinking that the current goes into a resistore as a + current and out a  current ?
Have a look in the local cemetary sometimeSorry Stanley baker no idea what you mean.
