What is the function of Bypass diode in the test terminals of a pressure transmitter?
The function of the bypass diode is to allow the loop current to be measured without disconnecting the current loop connections. It therefore allows for a quick measurement of the loop current without disturbing any control or monitoring equipment that is connected to it. This is achieved by simply connecting an ammeter across the diode. If the voltage drop across the ammeter is less than that of the diode (about 0.6V) then all of the loop current will flow through the ammeter rather than the diode. The ammeter is therefore able to measure the loop current.
Why tunnel diode are used in negative resistance region?
because that the tunnel diode is a standard pn junction diode in many respect except its highly doped pn junction so it has some characteristics in the negative resistance region another that its a standard diode
What is a large slower acting diode?
it is a rectify diode
What is the difference between a 1N4007 diode and a 1N4007S diode what does the s do?
The difference in the 1N4007 diode and the 1N4007S diode is the voltage. The 1N4007S has a higher voltage but the meaning of the S is not listed.
What is schotty diode?
Its schotlky diode. schotlky diode is metal semi conducter junction. It has fast switchng speed. The cutting voltage of schotlky diode is about 0.2 volts.
How do you define zener diode terminals?
two terminals
The terminals of a diode are called the?
anode positive potential cathode negative potential
Is it possible to observe the terminals of diode by observation?
yes, it is possible to observe the terminals of diode by observation. anode has black in color & kathode is colored with white.. white ring side is kathode..
What is the difference between potentiometer and light-sensitive diode?
potentiometer is not sensitive to lightpotentiometer has three terminals, diode has two
What is the definition of silicon diode?
A silicon diode is a tiny electronic component having two terminals, usually a switch or limiting device.
What diode is used as voltage controlled capacitor?
It is called a varactor or a varicap diode. Its capacitance varies nonlinearly with the reverse voltage applied to its terminals.
Can you use transistor as diode?
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.
How do you give a demo on the only diode?
Its a power full Semiconductor device now we have..It is having Two terminals
Why there is no current when two terminals of the diode are shorted?
There must be a break in the power supply elsewhere in the circuit. I suggest a blown fuse The only diode that generates electricity is a solar cell
What is the composition of typical diode?
The typical diode consist of terminals. Terminal A is anode negative, Terminal B is cathode bearing positive energy. An epoxy dome secures lead frame.
What is the purpose of an cathode and an anode in a diode?
The cathode and anode are simply two terminals of a semi-conductor junction. In a normal diode, forward bias occurs when the anode is more positive than the cathode.
How do you find diode IN5408 is usuable?
You need an ohmmeter or multimeter (set in resistance measurement mode). Choose the 1kOhm range. Connect the meter's wires (red & black) each to the diode's terminals, then switch the terminals. In one case you should see a meter reading that is substantially lower than the other. If that is not the case (both read high or both read low), the diode is probably faulty.
