What will be the output voltage if reference voltage is open circuited in a series voltage regulator?
unregulated voltage minus series regulator transistor drop.
What is Si transistor?
A silicon transistor is a transistor made of silicon.
What happen if the series resistor in a forward-biased p-n junction is short-circuited?
The junction (diode or transistor) will be destroyed.
What are the Similar transistor for 221334 PNP transistor?
Similar to a 2N3906 PNP transistor
What is rt in electronics?
I believe that is resistor transistor technology TTL transistor transistor logic
Can be replace npn transistor series regulator with pnp?
no
What will be the output voltage if reference voltage is open circuited in a series voltage regulator?
unregulated voltage minus series regulator transistor drop.
How does a series regulator maintain the output voltage at a constant level?
A series regulator maintains the output voltage at a constant level by constantly changing the effective resistance of the pass device, usually the output transistor.
What does the prefix designation of TTL series indicate?
Transistor Transistor Logic
If a television high voltage regulator opens what is the likely to be the symptom?
In most sets, the HV regulator actually regulates the B+ voltage to the horizontal output transistor and the flyback transformer. A bad regulator indicates high current or loss of horizontal drive. Check the flyback transformer, the HO transistor and also look for proper waveform and voltage from the horizontal driver transistor/chip.
How do run 380V motor in 440V supply voltage?
You can use a voltage regulator IC/transistor that can take any input voltage (to a point) and spit out whatever voltage you want, depending on your application (in this case 380 volts) then be sure you build a regulator with the correct IC/transistor. Hope this helps!
A 7812 transistor is pnp type?
The 7812 is not a transistor. It is an integrated circuit, a voltage regulator designed to regulate an input voltage down to 12 volts output. It typically comes in a TO-220 case, and has three leads, so it sure does look like a transistor though!
How can you reduce 48volts dc to 12 volts dc of 3amps using LM317?
A reduction of 36 volts (48 - 12) with 3 amperes of current rating in a series regulator represents 108 watts. That is quite a bit of heat. It would be better to use some kind of a switching regulator instead. Answering the specific question, however... The LM317 is only rated 1.5 amperes, so to get 3 amperes out of it you will need a power transistor that boosts the regulator's rating. You still can't avoid the power dissipation, however, so my original answer of using a switching regulator is apropos. As an alternative to the LM317, you can use the LM150 series, rated to 3 amperes, or the LM138 series, rated to 5 amperes.
DC blocking in a transistor is achieved by?
Including a series capacitor in the input and/or output circuit of the transistor. If the capacitor in the output circuit is omitted there will be a dc component in the output.
What is the working of a Darlington amplifier?
it is a combination of two transistors connected in series. the emitter of transistor t1 is connected to the base of transistor t2 . now the total circuit acts as a single transistor. this combination will gives high gain, as the gain is multiplied.
How can you designed transistor using diode because no available transistor?
You cannot build a transistor with two diodes. Even though the static junction characteristics of a transistor "looks like" two back to back series diodes, there is a relationship between the two junctions that cannot be matched by just connecting two diodes together.
How does a transister work as an amplifier?
The name is your clue: a transistor and a resistor (the load) are put in series. The output signal is taken from the load resistor. A small input signal (to the third lead of the transistor) will cause the transistor to change resistance ... thus you can get a large output from a small input Amplification.
