How do you identify leads in a diode?
Basically, one end of the diode should be grey, while the rest of the diode is black. The grey end is the cathode (out) end, while the black end is the Anode (in) end. So the flow is from anode towards cathode. Using a multimeter, set the meter to the diode symbol (can't show graphics on Answers) but it is a triangle on its side (shaped like an arrow fired from a bow, with 3 lines meeting at the tip of the arrow). Put the red positive probe against the anode wire, and the black negative probe against the cathode wire. You should see a reading indicating that electricity is being detected. Now reverse the probes and you should fail to get a reading (as the flow is only one way). You now know which end is which for certain. (Some diodes (which come in many sizes and capacities) may not be marked at all, so using a multimeter is sometimes essential.) There is more to diodes than in my answer, so I advise a search on youtube for videos on diodes, so gaining greater depth and clarity on diodes than I have been able to put here.
Is stranded copper wire a better conductor than solid copper wire?
no
A piece of copper wire was cut into n equal parts these parts are connected in parallel how will the resistance of the parallel combination compare with the resistance of the wire?
The resulting resistance of the parallel combination will be the resistance of the original wire divided by n squared.
What is Another name for barbed wire barricade?
abatis
How many simple machines are in wire cutters?
Two levers in the form of handles, two wedges in the form of blades and another lever in the form of a rotating attachment point
What is a synonym for electrode?
According to Thesaurus.com synonyms: copper cathode, inert anode, inert cathode,plate, wire, zinc anode
Why flow of current from cathode to anode still the flow of electrons is from cathode to anode?
The conventional current flow from cathode to anode is a historical convention established before the discovery of electrons. Electrons, being negatively charged, actually flow from the anode to the cathode in an electric circuit. However, because the flow of positive charges is analogous to conventional current flow, it is discussed in terms of current flowing from the cathode to the anode.
How do you wire a beacon light?
To wire a beacon light, add the proper resistor to the LED. Then bypass the decoder and wire the LED's cathode and anode to the opposite rails.
How does electrical charges?
the electrons goes from the anode to a wire making the anode positive then goes to the cathode making the cathode making it negative SO WHY DO U CARE IS THE WORLD GONNA ENDI WOULD PERFER ENGLISH PLEASE DO U
How do you wire Bi color LEDs?
Treat each color as a separate LED and wire accordingly. Be sure to observe the polarity of the component (anode and cathode +/-)
How do you wire Bi-color LEDs?
Treat each color as a separate LED and wire accordingly. Be sure to observe the polarity of the component (anode and cathode +/-)
What is the short and long legs of LED called?
Cathode (negative) is the shortest leg and there is a flat edge on the base of the LED, and it must be connected to the negative wire or "-" connection. Anode (positive) is the longest leg, and must be connected to the positive wire or "+" connection, as electricity will only pass through a LED from positive to negative.
What is working principle and construction of bridge rectifier?
A full wave bridge rectifier converts AC (Alternating Current) into DC (Direct Current) with an AC component. To achieve DC only, the output of the bridge rectifier must have the AC component removed by bypassing it, usually with capacitors. It consists of 4 diodes in a bridge format. During one half of an AC cycle, two of the diodes conduct and on the other half a cycle the other two conduct. Diodes allow current to flow in one direction only.

How do you make eletricity from fruit and vegetables?
Fruit can produce electricity by puting an anode and a cathode in them preferably made from different metals join them to a wire and you will have a current.
What is the term for the flow of electric charge?
the electrons goes from the anode to a wire making the anode positive then goes to the cathode making the cathode making it negative SO WHY DO U CARE IS THE WORLD GONNA ENDI WOULD PERFER ENGLISH PLEASE DO U
How does a galvanic cell work?
.. A redox reaction at two electrodes causes electrons to flow.
How do you identify the leads of a diode?
There are two wires on a diode: Anode (positive in) and Cathode (negative out). A diode may have a grey band at the cathode end, and black at the anode end. Diodes come in many sizes and capacities, some with clear markings, some without, so there are times when a multimeter has to be used. Set the multimeter to the diode setting (looks like an horizontal arrow fired from a bow, with three lines meeting at the arrow-head's tip). Touch one wire with the red + probe, and the other wire with the black - probe. If there is no reaction, electricity is not flowing. Reverse the probes and you should get a reaction showing that electricity has been detected. So the red probe marks the anode wire and the black probe marks the cathode wire. If there is no reaction, whichever probes are tried, then the diode is dead.
