Ohm's law

Posted in

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 akan dihambat by these 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 expressed with:



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