You can use a transistor as a diode if you connect the base to the collector.
Any forward current through the base-emitter junction would cause a corresponding increase in the available current through the collector-emitter junction. Since the base-emitter and collector-emitter junctions are in parallel, this would effectively be a diode, but a true diode would be a better solution if diode functionality is what seek.
A: There are actually two diodes, per se, inside a transistor. The base to emitter diode will suffice. By tying the collector to the base it will in effect be two diodes in parallel.
transistor. This word is a blended form of transfer of resistor. The legs of transistor (collector, emitter,base) transfer the resistance. So it is called as transistor
bad
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.
Its not!
Transistor is called Bi-Polar device because the current can be flow due to electron and holes, hence it is called bipolar.
Most transistors have three leads. This is true even in power transistors which use the external case or housing to connect to the collector, because the circuit which uses the power transistor must still use three wires to connect to it.
A Rhetorical Question
Transistor=Transfer+Resistor. When Transistor operates in active region its input resistance is high and output resistance is low. So,We can consider transistor as a device which transfers its resistance from high to low. And by this property transistor amplifies input signal.
It is called a response.
When the out from a transistor is the exact replic of the input signal then it is called unmodulated signal i e. there will not be any change in frequency voltage power etc
A small signal NPN transistor used for general purpose audio amplifiers and switching.
There's no question here.
