A transistor is a component which is the main building of the development of electronics. Semiconductor devices are typically classified into two major divisions, namely: Juction Bipolar Transistors (BJT) or commonly called the A and Field Effect Transistor Transistor (FET). This chapter, and the next several chapters, will discuss the characteristics, configuration and use of transistors in electronic circuits. In ...

As in the current measurement, measurement of electrical voltage with a voltmeter also has limitations, prisoner in Rm meter measuring limit voltage limiting capability. Raising the voltage measurement performed by placing detainees at the meter base ser Rs. Prisoners energized Rs series of Is, which flows through the meter for Im Rm. design Voltmeter When a D’Arsonval meter coupled with ...

The success of the installation of the control panel manufacture electric motors basically depends on how to understand thoroughly (carefully) according to specifications. The design of the equipment, circuit diagrams, component selection and installation of the motor control can vary according to the complexity of the system and component selection of the service providers. Besides this, for the simple system ...

KWH Meter is used to record the amount of electrical energy used by a power load be it resistive, inductive, capacitive. Everything will be recorded by the KWH Meter tool. Based on how it works (design) KWH Meter is divided into two parts, namely: 1. KWH meter with motor prinsif, 2. KWH meter with static meter. Static meters are used ...

In general, the power supply is always equipped with a regulator tegangan.Tujuan installation of the power supply voltage regulator is to stabilize the output voltage when the input voltage changes occur on the power supply. Another function of the voltage regulator is to protect against the occurrence of short circuit in the load. One method that can generate a stable ...

Magnets or magnetic contactor switch is a switch that works by magnetism, meaning that the switch can work if there is a magnetic force. Magnet serves as towing and release contacts. A contactor must be able to drain and disconnect the electric current in normal circumstances. Electric current flowing normally is an electric current flowing during the termination does not ...
