Judging from its function, the resistors can be divided into: 1. Fixed Resistors (Fixed Resistors) Namely resistor whose value can not be changed, so always fixed (constant) .Resistor is usually made of Nikelin or karbon.Berfungsi as a voltage divider, regulate or limit the current in a circuit as well as enlarging and reducing stress. 2. Resistor Variable (variable resistor) Namely ...

Dari persamaan RX terlihat bahwa RX dapat dinyatakan dalam IM atau terdapat hubungan antara resistansi RX (yang kita ukur) dengan arus melalui meter IM. Perhatikan pula bahwa grafik hubungan antara RX dan IM disebut sebagai kurva kalibrasi. Berikut ini diperlihatkan contoh bentuk kurva kalibrasi untuk suatu ohmmeter seri. Gambar 8.5 Kurva Kalibrasi Ohmeter Seri Dari kurva kalibrasi, terlihat bahwa skala ...

KWH Meter digunakan untuk mencatat besarnya energi listrik yang dipakai oleh suatu beban listrik baik itu resistif, induktif, kapasitif. Semuanya akan dicatat oleh alat KWH Meter tersebut. Berdasarkan cara kerjanya (rancangannya) KWH Meter dibagi menjadi dua bagian yaitu ialah : 1. KWH meter dengan prinsif motor, 2. KWH meter dengan meter statik. Sedangkan meter statik digunakan untuk meter-meter arus searah. ...

Basically all the materials have resistive properties but some materials such as copper, silver, gold and metal materials generally have a very small resistance. These materials deliver the electrical current very well, so-called konduktor.Kebalikan of conductive materials, ie materials such as rubber, glass, carbon has a greater resistance resist the flow of electrons, so-called as an insulator. Resistors are the ...

In Figure 16 a single wire / wire node acting as a stator winding and a magnetic rod acting as a rotor illustrates how the AC voltage / voltage is produced within a basic alternator. If two wire / wire nodes again, which are 120 degrees apart, are added to our base alternator, then two separate seperate voltages will be ...

NE555 IC that has an 8-pin (leg) is one of the electronic components is quite well known, simple, and versatile with size less than 1/2 cm3 (cubic centimeter). Basically, the main application is used as the IC NE555 timer (Timer) with monostable circuit operation and Pulse Generator (pulse generator) with astable circuit operation. In addition, it can also be used ...
