A circuit or linear network, active and resistive containing one or more sources of voltage or current source can be replaced with a voltage source and a series resistance (Theorem Thevenin) or a current source and a parallel resistance (Theorem Norton). The voltage is referred to as a replacement voltage UT and current source called current source IT penggnati resistannya’re ...

A. Heat Resistor (NTC) NTC (Negative Temperature coefisien) is a resistor with a negative temperature coefficient is very high. Thermistors of this type is made of oxides of transition metal group element (eg Fe2O3, NiO CoO and others – others). Oxide – oxide has a very high resistivity in pure substances, but can be transformed into a semi-conductor by adding ...

VDR is “Voltage Dependent Resistor” semiconductors in principle as a merger is anti-parallel on the series connection PN Junction. When a variable DC voltage is connected to the VDR regardless of the polarity, current flows cause the voltage across the PN Junction connected in series. Therefore, VDR has high voltage current low voltage and high voltage current low persistence. Gambar.3.14 ...

One advantage of this type of capacitors is to have the ability to store charge Q = CV is greater when compared to other types of capacitors other, and commonly used as an element grader (filter low frequency) to the power supply circuit and can also function as coupling or decoupling the amplifier – amplifier for audio frequency (AF). High ...

A. Mica Capacitors Mica is a naturally occurring substance that is due to the physical structure of the crystal is similar to the plate, making it can be laminated into sheets of very thin one. Mika is a very stable type of materials with high permittivity, so that the capacitor capacitors made from these types of materials can produce a ...

Measuring tool is a tool that can be used to determine the results of the comparison between a quantity you want to know the standards used. An important function of the measuring instrument in particular measuring devices of electrical quantities is to know the value that has been determined as eligible limitation or failure of equipment or electricity network will ...
