Yes, a full-wave rectifier can be made with only four diodes. No transformer is required.

That would be a metal-oxide-semiconductor field-effect transistor.\n\nThree terminals are source, drain and gate.  The presence or absence of electric charge at the gate modulates the flow of current between source and drain.

If memory serves... the J-FET has three terminals.. the gate, the source and the drain. It works, almost, like the plumbing parts the terminals are named after. The current is allowed to flow from source to the drain as the voltage at the gate is raised.

amplifiers are a common use of transistors. Basically any circuit where you want to control a large voltage or amperage with a small voltage is done with a transistor. They are a fundamental building block in modern electronics as well.

A transistor is a semiconductor device that uses a small amount of voltage or electrical current to control a larger change in voltage or current. Because of its fast response and accuracy, it may be used in a wide variety of applications, including amplification, switching, voltage stabilization, signal modulation, and as an oscillator. The transistor is the fundamental building block of both digital and analog circuits — the circuitry that governs the operation of computers, cellular phones, and all other modern electronics. Transistors may be packaged individually or as part of an integrated circuit chip, which may hold thousands of transistors in a very small area.

Hi,\n\nThe circle is also called envelope or enclosure. It has the functions defined here: http://www.kodkodkod.com/files/symbolenvelope.htm\n\nFor a BJT transistor, the envelope can serve the purposes mentioned in 1) 2) and 4). However, it is not really necessary to have the "circle" if 1),2) and 4) are not required. Indeed in many college textbooks and research publications in IEEE, people just omit the circle.\n\nPlease bear in mind that circuit symbol is the mean to represent the circuit in a readable way. Therefore, if the circle helps you to present the circuit, then use it (e.g. if you have bad hand drawing). If the circle makes your diagram more confusing (e.g. you have many transistors), then omit it.\n\nKodKodKod Learning Consulting -Here you get the answers!\nhttp://www.kodkodkod.com\nTo submit questions: http://www.kodkodkod.com/index_files/submitquestion.htm

i have my difficulties to determine what you mean with PLC  but in case you talk about chip technology or the standard transistor in semiconductors the answer could be:\nthere is semiconducting material which is mixed with specific conducting material. \nout of this process you can have material that prefers negative charging or positive charging, N or P material.\nnow the function of a transistor is that you put 3 layers of such material together in a NPN or PNP configuration, connect the base of the transistor to the material in the middle, and two other connections to that material to both 'ends'.\nnow if you put some voltage to the outer connections nothing much will happen except you start filling up the middle section with a negative or in other configuration a positive charge. In this case the whole setup becomes 'conducting' and you can observe current running from one side to the other.\nthis can be used as a switch, or a amplifier in electronics\nnow the difference is which kind of charge you prefer to make the transistor switch.\n\ndoes this solve your question ?

The same,\n 1. An equivalent circuit of a NPN transistor is two diodes tied anode to anode; one cathode being the emitter, the other the collector, and the junction of the anodes is the base.  \n\n  2. When a NPN transistor is doing-its-thing, there is always a constant 0.6 volt drop between the base and emitter, i.e., the base is always ~ 0.6 volts more positive than the emitter--always! \n\n  3. There is no output at the collector, until the base has reached ~ 0.6 volts and the base is drawing current, i.e., any signal that appears at the base that is not up to ~ 0.6 volts (and not drawing base current), is never seen at the collector.  \n\n  4. The base requires a current, not a voltage to control the collector current.  \n\n  5. The collector is a current source: it does not source a voltage.  \n\n  6. The collector appears to output a voltage when a resistor is connected between it and power.  \n\n  7. The collector is a high impedance when compared to the emitter.  \n\n  8. The transistor can output an amplified signal either from the collector or the emitter (or both).  \n\n  9. When operating with a collector resistor (RL): the output voltage from the collector is an amplified voltage.  \n\n10. When operating with only an emitter resistor (Re): the output voltage from the emitter is not an amplified voltage, because it is always ~ 0.6 volts, below the input (base) voltage--hence the name voltage follower. But because the emitter can source large amounts of current to the "LOAD," it can be said, there was CURRENT amplification. \n\n11. The collector--being high impedance--cannot drive a low impedance load.  \n\n12. The emitter--being a low impedance--can drive a low impedance load.  \n\n13. The voltage gain from the collector is greater than one (Gv > 1).  \n\n14. The voltage gain from the emitter is less than one (Gv < 1).  \n\n15. Both the collector and the emitter: output ~ the same power: E x I = P.
