Kirchoff´s Laws

Whats is a junction?

Ajunction is any place(in a circuit) where two or more wines core together/meet.

What is a Branch?

A branch is anything that connects two junction together

Junction 1=-1-12+13=0
Junction 2=11+12-13=0

The are 3 posible loop rule equations in this circuit;

Top rule

Bottom loop

Complete loop

You must decide of the curren: Clockwise or anti cockwise

He doesn`t mather wicht direction you choose but you must label this on the circuit diagram.

If a current passes through a battery negative(-) to positive(+) then the voltage is positive.

If a current passes through a battery (+) to (-). The voltaje is negative.

Batteries:

-      +    then the voltage is positive
+     -     then the voltage is negative
