The Diode Check setting on a DVOM is a special ohms setting that presents enough voltage to the tested device to conduct, if it were a diode. Old style VOM's did not have this problem, because they usually used a battery greater than 0.7 volts to run the ohm's scale. Modern DVOM's, however, can use very small voltages to measure ohms, and that would not cause a diode to conduct. The Diode Check setting fixes this limitation.
What else can I help you with?
What type of diode is a HVR-1X4 diode?
It's a high voltage diode, typically used in microwave ovens.
When testing circuits on modern vehicles the DVOM being used should have input impedance of at least?
10 mega ohms.
What is the function of zener?
zener diode is a revers bias diode which used for voltage regulation.
What is the freewheeling diode operation?
Very often in translations from German to English the term 'free wheeling diode' for 'Freilauf-Diode' is used. Generally the correct translation for this term would be 'recovery diode'. The usage of the term 'free wheeling' only will be correct in mechanical aspects, e.g. the rear wheel of a bicycle or the clutch of the transmission line of a car.
When does the diode not allowed to flow the current?
A diode is a one-way gate for electrical current to flow through. You must have the right size diode for the amount of current that will be used in your circuit. The stripe on the diode is your output end. That is, the current must enter your diode at the non-stripe end and leave at the end with the stripe. This coincides with the diode symbol used on your schematic. If your diode is in backwards, the circuit will not work as the gate in the diode will block the current just the way it should.
Can a diode be used as rectifier diode?
yes, diode can be used as rectifier diode to convert ac to dc
What is the function of diode what is the function of diode?
A diode is used primarily as a Rectifier
Can diode be used as rectifier?
yes ofcourse diode can be used as rectifier but it's an uncontrolled rectification.
Is it pn junction diode used as voltage regulator?
zener diode
What type of diode is used as a variable capacitor?
varactor diode is a correct answer
What type of diode is a HVR-1X4 diode?
It's a high voltage diode, typically used in microwave ovens.
What is the difference between p n junction and zener diode?
The difference between the pn-junction diode and the zener diode is that the pn-junction diode is used for rectification while the zener diode is used for rectification and stabilization. Also, the zener diode can function in the breakdown region while the pn-juntion diode can not function in that regime.
What is use of the diode?
The use of the pn diode is for rectification. It can also be used as a switch.
Does a zener diode acts as a switch?
A zener diode cannot be used as switch.
What is the different between photo-diode and LED?
A Photo-diode is used to receive light. whereas the L.E.D. is a Light Emitting Diode.
When testing circuits on modern vehicles the DVOM being used should have input impedance of at least?
10 mega ohms.
When testing circuits on modern vehicles the DVOM being used should have input impedence of at least what?
10 mega ohms.
