To complete the calculation of electrical circuits or meshes, a natural scientist from Germany named Gustav Kirchoff has found two ways then this way becomes law known as “Kirchoff’s Law”.<\/span> From the above picture I2 and I3 current direction opposite to the direction of the current I1, I4 and I5.<\/span> So at the branching point A valid:<\/span> Examples of application of Kirchoff’s Law 1 is like the circuit below as an application as a flow divider.<\/span> The equations obtained from the circuit above are as follows:<\/span> Kirchoff’s Law II of voltage<\/strong><\/span> In direct current electrical network to meperoleh a certain voltage can use a combination of certain prisoners, the circuit is called a voltage divider circuit.<\/span> Simple voltage divider circuit which can be shown by Figure 4.6 below<\/span> The amount of current flowing in the circuit is<\/span>

\n<\/strong> Kirchoff’s Law I for series or grid reads: “The algebraic sum of electric current at a branching point is always equal to zero” In figure 4.1 Kirchoff I explained the law as follows:<\/span>

\n I1 + I4 + I5 – I2 – I3 = 0 or I1 + I4 + I5 = I2 + I3<\/span>

\n<\/strong> Law Kirchoff II relates to electrical circuit is closed which states: “In a closed circuit, the algebraic sum of the voltage (V) with losses of voltage is always equal to zero” This law is generally written by the formula: \u03a3V = \u03a3 R x I in Figure 4.5 with no regard to the offset voltage in the battery (the battery prisoners considered small) then: V – (IR) = 0 or E = I.
