Which side of diode is anode and which is cathode on the diode in a schematic?

The anode is the arrow shaped end, while the cathode is the bar shaped end. You can remember this by recalling that current flows from anode to cathode in an ordinary diode; well, that is, if you use the trick of assuming that current is hole flow, rather than electron flow, a useful and common convention. The exception, of course, is the zener diode, where current flows in both directions, but at different potentials. In this case, there are two 45 degree angled bars at the end of the cathode symbol, and the normal configuration of current flow is cathode to anode, backwards with respect to an ordinary diode.

How can you reduce back current while using relay?
You put a diode in parallel with the coil. The cathode end of the diode connects to the plus side of the coil and the anode connects to the negative side. The cathode is usually marked with a line at one end of the component.
What condition under is a diode never intentionally operated?
In the reverse-bias condition, the negative terminal of the source is connected to the anode side of the circuit and the positive terminal is connected to the cathode side.
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
What is the symbol for a thyristor?
It is a standard diode, with an additional line leaving the cathode (- side) for the gate. See wikipedia link.
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..

In electrolysis electrons move between two metal strips called?
Electrodes, the positive side is called the Cathode and the Negative side is called the Anode.The anode and cathode. The anode is positively charged and the cathode is negative.

What invention in the 1940 was first used in a car using 2 pieces of metal and is rechageable and is now smaller?
the invention was a tri-ode diode which is an electronic gas filled tube with an anode and a cathode and one more switching element. The anode is actually the negative plate and the cathode is the positive side. The third element is a switch for on and off.
Is the anode side of a batteries the positive side or the negative side?
" Anode " is generally refer to POSITIVE. Cathode generally refer to NEGATIVE. But these terms are use for different applications ( For example: you wouldn't refer to the POSITIVE side of a battery as ANODE or NEGATIVE side as CATHODE, it commonly refer as positive or negative when you are dealing with battery application etc. )
How do you find the AC input and anode rathode of a brige diode using VOM?
A: On a bridge rectifier there are two diode connected in series and in series with the load they only conduct once per cycle positive then the other two take over for the negative cycle . At the load positive the diodes will be two cathode tied together at the negative side there is two diode where the anode are tied together. either cathode anode tied together that is the ac. You cannot use an ohmmeter to check for faults this way since the load and the transformer resistance are in the way. Must remove the bridge to check it.
What is the negative leg of an LED called?
The side of any diode that must be negative in order for the diode to conduct is the "cathode".
What are the parts in a diode?
That depends on the diode, however I will talk about a very basic one. Simple version: One side is called the anode, the other is the cathode. Current only flows from the anode to toward the cathode. It is blocked from traveling in the other direction. Less simple version: I am including this since you asked about the parts "in" a diode and not the parts "of" a diode. Diodes are semiconductor devices and are constructed with two pieces of semiconductor material (silicon, germanium, etc), one of which has been designed with extra electrons in it (cathode side) and one with extra spots for electrons to occupy (anode side) . Remember current flowing in one direction means electrons are traveling in the opposite direction. Now, if you apply enough positive voltage to the cathode, current will flow to the anode, but it will damage the diode if it is not designed to handle it. Some diodes are even designed to be used this way (look up zener diodes). To really understand the physics of what is happening in these materials, you need some knowledge of quantum mechanics (not joking) but that is beyond this question. Hope you got what you needed.

Why it is not a npnp diode in place of pnpn diode?
I think there is no difference between PNPN diode and NPNP because if u look at the basic structure of this diode from anode side it is a PNPN diode and if u look at it from the cathode side it is a NPNP diode.......actually it is a four layer silicon device with two terminals...it consists of 3 junctions..it acts as a switch during forward bias condition..... i hope it's the correct one....if I am wrong please post the correct answer so that i can correct myself.....
Does a full-wave rectifier work if there is no ground?
You can use it as a floating PS by connecting the anode side to - supply and the cathode side to +
