Hukum Ohm

type='html'>Hukum Ohm
States that "the voltage across the various types of materials are proportionate with the straight flow of the stream." Mathematically expressed by:

Ohm's law formula can be derived as follows:

V is the voltage (in volt), I is the current that flows (in ampere) and R is resistansi or obstacles (in ohm, Ω) which is 1 ohm value is equal to 1 volt / ampere.
Resistansi is a measure of how large flow by preventing elements. Reverse of resistansi (1 / Ω, S) is called with konduktansi (G). Konduktansi is a measure of how good flowing currents akan allowed in the series. The mathematical relationship between resistansi and konduktansi stated with

Example 1
Determine the current that flows in the series when a 12 volt battery is connected with a resistor of 2 Ω!
Answer:

Example 2
Specify resistansi of 44 fluorescent light wall W, which when connected with the voltage of 220 V will then flow currents of 200 mA!

States that "all the algebraic number of the flow enters a knot / point in the series is a zero" or "the amount of flow that enters the knot in a series with the same amount of flow that is out of the knot."
Expressed mathematically with

As an illustration shown in the picture below:

So based on the law applicable kirchof flow:

-Hukum Kirchoff Tegangan

States that "the amount of voltage that all algebraic corral a road closed (loop) in a series of electricity is zero." Mathematically expressed by:
