Posted in

Adaptor ini mempunyai output 12 volt yang sudah teregulasi dengan baik

The adapter has a set of output 12 volt which is teregulasi well. If the components that were installed in accordance with the scheme under the set of the series of this adapter safe burdened to 5 ampere, if you want this adapter is able to be burden with a greater flow you can add a power transistor (2N3055) and replace with dioda referrer dioda that have ampere higher. Exodus series of this adapter can be used to run the tape the car, the radio transmitter, CCTV cameras, and other electronics equipment.

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!
