A series pass transistor allows the voltage to pass to the rest of the circuit. The current goes around the part of the circuit like an IC for example, that would be destroyed if too much current were to pass through it.
Series pass transistors allows small voltages and small current parts, to control
higher voltages and currents than they presently cannot do by themselves.

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 does a transistor tester work?
very unreliably it can only tell if it is good but not how good and will tell you if bad but not how bad. it is only good for pass no pass testing.
How do you test a transistor using cathode ray oscilloscope?
Yeah...its possible to test the transistor using Cathode Ray Oscilloscope (CRO). CRO provides a function called "Component Testing". Just connect the transistor terminals between two pins provided by this function and you can observe the patterns on the CRO screen. Normally, in case of transistor, The operation is divided in few parts. 01. Observe the pattern for CB configuration. ---- For this, connect the terminalsfrom CRO between this Collector and Base terminals and you can observe the pattern shown by CRO. Same procedure should continue for CE & BE configuration so as to test the transistor.
Use commutating capacitor for bistable multivibrator?
it is about thefiltering of the ac signal from the circuit. when transistor2 switched on, collector terminal is suddenly shorted to ground and voltage at collector2 drops to vce from vcc.it cause a negative voltage pulse. the negative pulse coming at the collector of 2nd transistor passes to base of 1st transistor and thus transistor1 is switched off. commutating capacitors will allow to pass the ac signal only. so the negative pulse at the 2nd collector alone is feed to the base of 1st transistor. that is function of commutating capacitor
What does the prefix designation of TTL series indicate?
Transistor Transistor Logic
What does an resistor do?
Most of the time emitter resistors are used to set the bias point of the transistor. Occasionally emitter resistors may act as fast blow fuses to protect a power transistor. In series linear voltage regulators an emitter resistor on each pass transistor to the regulated node is there to equalize current sharing between the pass transistors. In other words it depends on the circuit design.
What is the function of the legs on a transistor?
as the name suggest transistor means to transfer resistor, it is an electronic device,
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 is a pass transistor?
It sounds like you are talking about a band-pass filter. The transistor would be part of a circuit that detects and allows certain frequencies to pass through it. These are used in signal processing circuitry, particularly audio equipment. This is how equalizers work, 'Bass', 'Treble', 'Mid' knobs. a pass transistor has nothing to do with frequency . by definition it will pass the heavier currents of a regulator.for instance therefore the term pass.

Can be replace npn transistor series regulator with pnp?
no
How transistor helps to pass dc across capacitor?
It doesn't.
Function of resistor capacitor and transistor on integrated circuit?
resistor
How you will compare pass transistor with transmission gate logic?
The use of transmission gates eliminates the undesirable threshold voltage effects which give rise to loss of logic levels in pass transistor logic.
What is a function of a transistor?
To allow current to flow in only one direction.
Function of transistor BC 558 in musical bell?
it cnverts to a low voltage.
