Electricity Check

Electrical equipment or electrical load in the electrical circuit that produces a particular work commonly represented as the resistance of a circuit. Figure 5.2 shows two electrical circuits that have different resistance. Figure 5.1 The lights in the Series and Parallel Relations Any electrical equipment has a certain resistance. The amount of resistance depends on the size and equipment needs. ...

Electrical Voltage

Electrons to the movement requires a driving engine, which is similar to a pump, which on one side of the electrical circuit electrons “pushed into”, at the same time on the other side “pull” electrons. This machine is hereinafter referred to as generator voltage or voltage source. Thus in one clamp of the excess electron source voltage (pole), clamp the ...

Electrical Charge

Number of elementary charge (usually in the event of electricity participate billions of electrons and thereby elementary charge) generates a particular electrical charge (symbol formula Q). Unit of electrical charge is set to 1 Coulomb (symbol C). In this case applies: 1 C = 6.24. 1018 elementary charge We have described that Strong current I = electric charge Q Time ...

Desain Wattmeter

Wattmeter adalah instrumen untuk mengukur daya aktif. Tersedia dalam dua bentuk yaitu analog dan digital. Daya aktif merupakan perkalian antara daya semu ( S ) yaitu perkalian tegangan ( V ) dan arus ( I ) dan factor daya (Cos α). Oleh karena itu wattmeter mempunyai dua kumparan, yaitu kumparan putar untuk mendeteksi nilai tegangan dan kumparan statis untuk mendeteksi ...

Operation Methods Motor

The system operator of the motor performed at the start, running and Stop. The success of an operation of an electric motor is not only determined to “Running Performance” motor, but is also determined by the “Starting Performance”. Selection of starting method is much influenced by several factors such as the capacity of the motor / purposes of starting current, ...
