at this time , I will try to share about an electronic component called a transistor . either way of working, and also how to measure it . therefore , read well and share this article a friend ... khi khi khi
as previously described , the transistor is a combination of two words , namely transfer and resistor that can be interpreted freely as amperes or regulate the flow of current flow. The triode is a term that means three electrodes , and in the resistor itself does have three electrodes , the base, emitter, and collectors . Transistors can be an electric current or voltage amplifiers also due to have a third electrode.
Another function of a transistor is a switch circuit breaker and power connector on the base or bases when given very large currents . to the workings of the transistor itself depending on what type of transistor used .There are basically two kinds or types of transistors. There BJT transistor or a bipolar junction transistor or also known as bipolar transistors and FET transistors or field effect transistor or also known as the transistor effect. Here's how the BJT transistor .
BJT Transistor : As the name implies bipolar transistor ( BJT ) using two polarities carry a payload to carry electrical current to the output channels .In the bipolar transistor ( BJT ) there is also a boundary layer called the depletion zone , which at the end of each electric current that will fit will pass through the barrier and was divided because of the depletion zone this.
Effect transistor ( FET ) Slightly different from the workings of the bipolar transistor .
Reviewed effect transistor ( FET ) , only use one type polarity or charge carriers of electric current . It is clear , in contrast to the bipolar transistor has two polarity charge carriers.To effect transistor ( FET ) , the current entry will not be divided into two streams such as the bipolar transistor . Due to the position where the depletion zone of the resistor effect contained in the second , the side not in the middle .
Actually, for the type or types of BJT and FET transistor itself same function, the difference is on how the transistors only. I hope this discussion can provide benefits to the reader .
how to measure transistor with ease
How to Measure Transistor is quite rare , and is not known by many people . But knowing how to measure a transistor is important to do regularly. It can be used as an indication of whether the transistor is still in good standing and eligible to be used or not . In measuring transistor we can use two kinds of tools that analog multimeters and digital multimeters . How to measure a transistor using this tool , relatively simple, and easy to do.
Results obtained was extremely accurate in determining the feasibility of a transistor . Therefore, both of these tools are excellent for people who are involved in the world of electro . including me
Here we will explain how to measure transistor by using these two tools.
How to measure the first transistor is using the analog multimeter . In the measurement is a transistor that uses an analog multimeter was divided into two types , namely Positive - Negative - Positive ( PNP ) and Negative - Positive - Negative ( NPN ) .
For type PNP , the first step you need to do is adjust the position of the switch in position X1K or 10k Ohm . Then connect the red probe to the base terminal and the black probe to the emitter terminal .
If the needle moves to the right , then the transmitter in a state that is worth taking. The last step , move the black probe to the terminal Collector and if the needle is still moving to the right means that the transmitter is in good condition
Do the same for NPN type . Just move the black probe to the base terminal and the red probe to the emitter terminal and insert the red probe on the terminal Collector .Meanwhile , in a way to measure a transistor using a digital multimeter approximately equal to the analog multimeter . For digital multimeter measurement is performed in a reverse way , from the analog multimeter .
Perhaps the different steps are just the beginning. If the first step in the analog transistor is positioning the switch in position X1K or 10k Ohm , the digital multimeter is to set the position of the switch in position diodes ( Ohm X1K or x100k ) .
In principle function digital multimeter to measure the diode and resistance in the same switch . To determine whether the transistor is still good or not , the screen on the digital multimeter shows the value of certain Voltage . Broadly speaking , both analog and digital multimeter do not have significant differences .
