Kata kontrol berarti mengatur atau mengendalikan, jadi yang dimaksud dengan pengontrolan motor adalah pengaturan atau pengendalian motor mulai dari pengasutan, pengoperasian hingga motor itu berhenti. Maka pengontrolan motor dapat dikategorikan menjadi tiga bagian menurut fungsinya, yaitu: Pengontrolan pada saat pengasutan (starting) Pengontrolan pada saat motor dalam keadaan beroperasi (pengaturan kecepatan, pembalikan arah putaran dan lain-lain) Pengontrolan pada saat motor berhenti ...

The hydrogen atom shows the simplest arrangement. Consisting of an electron and a proton (commonly called nuclei). Electrons as carriers of electric charges is called the smallest elementary charge. Electrons are elementary negative charge carriers, protons are elementary positive charge carrier. Figure 1.8 Figure atom schemes: a) a hydrogen atom b) carbon atoms Electron negative elementary charge equal to the ...

In everyday life, we can listen to the radio, watch television, use the refrigerator and electric irons. Have you ever watched an electric circuit in radio, television, refrigerator, or iron? Have you ever wondered why radio, television, refrigerator, or the board can function? The use of these tools require electricity. Electric currents occur because of the transfer of electric charges. ...

Measurements can be done with the prisoners in two ways: (1) direct and (2) Indirect. Measurement of prisoners are directly performed by using the ohmmeter. In essence the ohmmeter used to check the value of the electrical resistance. But because of the special characteristics, then the ohmmeter can be used also to examine the different elements dropping in a circuit ...

To overcome the boredom as described above, Maxwell introduced a method that calls the method of loop currents (current-loop) to solve complex problems of the electricity network. In this method Maxwell developed the rules that have been dikemukaan by Kirchoff’s Law Kirchoff in voltage and implement it through the loops are formed on the circuit concerned. By applying the current ...

When electrons move from a negatively charged end to end positively charged at a conductor, meaning it has made an effort electricity. Electric power is the rate of electron working on an electrical effort. This means that electrical power is the capacity of a business in which electricity is used. Electrical power is measured in watts (W) or kilowatt (kW). ...
