A transistor works by using a small amount of electricity to control a much larger supply of electricity, much like turning a valve to control a supply of water.
Transistors consist of three main parts - a base, a collector, and an emitter.
The base is the part for the larger electrical supply. The collector is the larger electrical supply, and the emitter emits that supply. By sending different levels of currents from the base, the size of the current can be regulated to the collector In this way, a very small amount of current may be used to control a large amount of current, like an amplifier.
ANSWER: A VOM can identify the transistor as NPN PNP just by checking the diodes inside the transistor. Example NPN positive lead to base should show low resistance to the other terminals

∙ 11y agoA curve tracer is best as it will allow measurement of all characteristics.
If you can't get access to a curve tracer, a go-nogo transistor tester is OK. Some multimeters have one built in.
If you can't get that you can test for opens & shorts using the ohms or diode scale of a multimeter. Test EB & CB junctions as you would test individual diodes and test CE both ways for leakage (CE should not conduct in either direction).

What is the meaning for sl100?
General Purpose Medium Power NPN Transistor
Is the pnp transistor in common collector can be replaced with npn transistor?
No. The PNP and NPN transistors are exactly opposite each other in polarity. You cannot just replace one for the other without redesigning the circuit.

When an NPN transistor is saturated its Vce?
is zero
Is BT169 a npn or pnp transistor?
BT169 is neither an NPN nor a PNP transistor. BT169 is a thyristor, otherwise known as a silicon controlled rectifier.
What is the difference between upstream and downstream in electrical network?
Generally upstream is closer to the positive (+) voltage source. In the case of an NPN transistor upstream of the transistor is the part of the circuit from (+) to the NPN collector pin. Downstream of the transistor is from the NPN emitter pin to the ground / sink / negative (-) terminal.
How does a NPN Epitaxial Silicon Transistor work?
epitaxial
Can be replace npn transistor series regulator with pnp?
no
How do you know if a transistor is a PNP or an NPN?
To know if a transistor is PNP or an NPN,the following should be verified:For a PNP transistor, the base-collector junction is forward biased while the base-emitter junction is reversed biased.For an NPN transistor, the base-emitter junction is forward biased while the base -collector junction is reversed biased.
