Week Three ^_^
How to determine the number of nodes, branches and loops in a circuit?
*Node - a point or junction where two or more circuit's elements (resistor,capacitor,inductor etc) meet is called node
*Branch - that part or section of circuit which locate between two junctions is called branch in a branch, one or more elements can be connected and they have two terminals.
*Loop - a closed path in circuit where more than two meshes can be occurred is called loop.

Kirchhoff's Law
Kirchhoff's Current Law (KCL)
- This is Kirchhoff's First law
- The sum of all currents that enter an electrical circuit junction is 0. when the currents enter junction is positive sign and the current that leave the junction have negative sign:
∑ IIN = ∑ IOUT
example:
Kirchhoff's Voltage Law (KVL)
- This is Kirchhoff's second law
- States that the sum of the voltage in a closed
loop is always equal to zero
∑ V = 0

example:
I1
+ I2 + I3 = I4 + I5

+ V2 + V3 + V4 = 0
Learning's :
Wow!!, its awesome,
where should i start?, By the way i learned so many things this past few weeks in our circuits 1, but this week it took me to long to understand our new topic the "kirchhoff's law" and definitely i learned how to find the nodes, branches and loops in a circuit.
