A: YES but not directly. for instance a discrete differential amplifier one side need to be a transistor to recover gain but the other transistor can be a diode since in real time that is the operative base to emitter current difference. .
The use of the pn diode is for rectification. It can also be used as a switch.
no we not use resistance in place of diode.
Backward diode
Diode is a two terminal semicon. Diode is a Switching device
Example sentence - The little red diode can be used as a pin on a tie.
the diode is forward bias ANSWER: A bypass diode is used to bypass circuitry as soon as the diode is forward bias by 0.6 volts The use it to bypass to prevent damage to the circuitry
voltage regulation
What we now know as TTL or Transistor to Transistor Logic is one way of building a computer chip. This has been done by a complex series of steps of manufacture that wasted much of what was made. TTL is used in instruments but the details of what instruments are used to make TTL these days in very technical and complex
scr is basically a three terminal device can be used as diode by leaving one terminal
its the simplest thing to do. There are three legs in a transistor, one each of collector, base and emitter. So if you need to use it as a diode, just connect either collector-base or emitter-base. Say, if you use an NPN transistor, then the base region will be the anode of diode and emitter or collector will be the cathode of the diode.
gas filled cold cathode glow discharge tubes.
you use an ohm meter
