Kirchoff's Law
The application of law is only used for analysis of simple sequences. To analyze a complex circuit you can use the kirchoff law of currents (Kirchoff's Current Law, abbreviated as KCL) and kirchoff's law of voltage (Kirchoff’s Voltage Law, abbreviated as KVL)

Kirchoff's Law 1 is Kirchoff's Law of Currents (KCL).
The total algebraic current flowing to the branching point is zero. The branching point is the meeting point of three or more currents to- or from a circuit element or voltage source.
In this law, an agreement is used that flows to the branching point are written with positive signs and those that do not go to (leaving branching points are written with negative signs.
I1 + I2 + I4 = I3, or
I1 + I2 - I3 + I4 = 0
Kirchoff's Legal Branch Point 1
Figure 9 above explains the meaning of KCL, where the value of the electric current through each prisoner can be determined. The definition obtained by the total value of the current flowing at a branching point is zero.

Kirchoff Law 2, Kirchoff Law on Voltage (KVL)
The sum of the total algebraic voltages in a closed loop read in one particular direction is equal to zero.
What is meant by the reduction of the tension in the law in relation to one particular direction is as follows:

Load network
a.For the element of detention
When the voltage is read from + to -, with the same read direction as the direction of flow I, then the value of V = RI is the voltage drop. To understand it give a positive sign (+) on V and a positive sign (+) on RI. Whereas when reading voltage is opposite direction
please provide a (-) V or (-) RI.

b. For voltage sources
If the read direction is from a to b, then it is a voltage drop that gives a positive sign to V. Or in other words, when following the + read direction from the voltage source, write a positive V. Instead of the reading of the poles - the voltage source is V with a negative sign.

Kirchoff's Law application series
Generally an electrical network consists of several loops and decoupling points with one or more voltage sources used. Once the value of a voltage source is known, then the quantity to be analyzed is the current value of each transmitter that enters or leaves the deviation point or voltage value of each detector of the network. the number of equations used to analyze a scale is not yet known, and the number must be as large as the number to determine its value.

Note to note:
The number of KCL equations that can be presented is equal to the number of subtraction points available.
The number of KVL equations is the same as the number of independent loops. A loop is said to be independent when it cannot be declared from another KVL loop equation.
Apart from the above, solving using a simplified series of series or parallel sections will be very helpful.
