What is the difference among a transistor a thermistor a thyristor and a resistor?
in simple terms:
a transistor is a device that allows you to control its resistance from a voltage or an input current.
a thermistor is a device whose resistance varies with temperature
a thyristor is a device that has quickly passed from a very high resistance to a very low resistance depending on n current / voltage input .. you must turn off the power to reset it to a high resistance.
a resistance to a fixed resistance – you choose it when you buy it!
what is the difference between a kangaroo, a rabbit, a cat and a bald eagle? sorry, I could not resist. Here are simple s to understand these components:
the transistors are 3-terminal junction semiconductors 2 (pnp or npn) that perform signal amplification, circuit impedance matching, level conversion signal, on / off signal switching and signal generation such as vibrators. there are bjt (double junction transistors), fets (field effect transistors and mosfet (metal oxide semiconductor fonts), igfets (insulated gate fetuses) and ujts (single junction transistors). also called scr (silicon controlled rectifiers), are passive devices whose resistance varies with increasing or decreasing the ambient temperature.The thyristors are also semiconductor devices with 3-terminal junction but at 3 (pnpn) designed to function as high-resistance switches at a very low voltage depending on the input voltage of a trip unit, the power supply must be turned off or off to turn off a scr off if it is used in a power supply configuration are passive devices which may have a fixed resistance or a variable resistor such as a potentiometer, such devices are used in the volume and The resistors control the amount of AC current. circuit, are used in voltage dividers and in circuit signal coupling devices. they are used in return circuits and in frequency dependent devices, current limiting for LEDs, rising or falling signals and impedance matching circuits.
