What else can I help you with?
When testing a shortened diode with a DMM and the positive lead is connected to the anode what should the reading be?
Assuming the DMM is rated to test diodes (not all are), meaning that it presents more than forward drop voltage to the diode, a shorted diode will test nearly zero ohms, usually in both directions.
What is the difference between a one diode rectifier and a two diode rectifier?
A one diode rectifier is called a half wave rectifier and only allows current flow for the positive portion of the sine wave. A two diode rectifier, or full wave rectifier allows positive current flow during the positive portion of the wave as well as positive current flow during the negative portion of the sine wave. This results in a much cleaner DC power signal. The addition of a capacitor in the output circuit will clean up the signal very nicely.
Why you use negative source in emitter biasing?
to get the base- emitter junction forward bias we should connect the negative of the diode with the negative of the battery and the positive of the diode with the positive of the diode so we should connect negative source in the emitter
What is the left leg of the led called?
Cathode and an anodeThey are called the "anode" and the "cathode", just like every other diode ever built.
What sort of diode do you need when putting a solar cell on a battery powered device?
There are two basic types of diodes; Silicon and Germanium. I would use germanium because it has a lower forward bias than silicon. I suspect that what you really want to know is how to hook up an isolation diode. This is a diode that is installed in series with the alternate power source to isolate one from the other. Whether you use germanium or silicon the way that you want to hook it up is pretty straight-forward. go ahead and hook the negative (black) lead of the solar cell to the negative (black) lead of the battery. Hook up the positive (red) lead of the solar cell to the anode of the isolation diode and the cathode end of the diode hooks up to the positive (red) lead of the battery. You can identify the anode and cathode ends of the diode by looking on the diode - you will see a little diagram that looks like an arrow with a straight line at the tip of the arrow. the straight line side is the cathode end. Unless you have a really big solar panel you could probably use a general purpose diode such as a 1N4001 silicon (available at radio-shack)Hope this helped you.
How do you identify the polarity of a diode when the tester is on diode scale?
Connect the positive lead of the tester to the anode of the diode and the negative lead to the cathode. If the tester displays a voltage drop or a forward bias reading, the diode is forward biased and the anode is positive. If the tester displays an OL or reverse bias reading, the diode is reverse biased and the anode is negative.
The terminals of a diode are called the?
anode positive potential cathode negative potential
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 clamping diode in a positive diode AND gate?
ttt
How do you identify p side and n side of a diode using a multi meter?
To identify the p-side and n-side of a diode using a multimeter, set the multimeter to the diode mode. Connect the positive lead of the multimeter to the suspected p-side of the diode and the negative lead to the suspected n-side. If the diode is connected in forward bias (p to positive, n to negative), the multimeter should show a low forward voltage drop. Conversely, if it is connected in reverse bias, the multimeter should display an open circuit.
What does forward bias on a diode?
when the positive terminal of the battery is connected to the positive terminal of the diode it is said to be in forward bias
What does forward bias on a diode means?
when the positive terminal of the battery is connected to the positive terminal of the diode it is said to be in forward bias
Why is a diode called unidirectional?
A diode is unidirectional because of the diode only conduct in forwardbias .As you know the diode have two terminal cathode and anode . and when the positive terminal of battery connected to the p-side and other terminal connected to the other terminal of diode then diode is called forward biased . and when it connection is just opposite then it become in reverse biased . so we can finally say that the diode is unidirectional
Describe forward-biased diode?
A specific amount of current is allowed to flow through a diode. If the current passing through the diode exceeds this specific value, the diode gets heated and is likely to be damaged. Therefore, in the biasing circuit of a resistance which limits the current passing through the diode within its specific value is called Forward biased diode. ANSWER: A forward bias diode is just a diode that it is conducting in the forward direction. Positive to anode and negative to cathode
A diode conducts only when it is?
a diode will conduct when anode is more positive than the cathode
Draw the equivalent circuit of UJT?
we can draw an equivalent circuit for UJT USING a DIODE and two resistors.draw a diode in emitter lead ..draw the two resistors in series.As rb1 in base 1 lead ..and rb2 in base 2 lead ..draw rb1 as variable resistor.And put a voltage to the ujt in order to get a positive voltage in base two lead.
How do you test polarity with a multimeter?
A: To begin with the leads polarity of the meter must be ascertain. Assuming the red is positive voltage then that lead will have a positive potential to check a diode connect the red lead to the anode and the black to the cathode and it should read some Resistance
