How does a Shockley diode work?
A Shockley diode uses a metal-semiconductor junction instead of a p-n semiconductor-semiconductor junction. This results in a device with a much lower forward bias voltage drop and much faster switching times.
Difference between optocoupler and normal diode?
Purpose: An optocoupler (or optical isolator) uses optics to isolate one circuit from another. The diode in the optical isolator is similar to an LED. The light from this LED controls the gate or base of a transistor. A diode has two terminals, an optocouple will have at least 4. A diode is used to control current flow direction; an optocoupler main purpose is to isolate one circuit from another. etc. etc.
What is a ordinary diode?
A diode is an electronic component that will only allow current to flow through it in one direction. It is analogous to the valve in a bicycle tyre, which only lets air in but not out (except when you press the release tab). So if you connect a diode in a simple DC circuit one way around, the circuit will be closed and any devices on the circuit will work. If you connect it the other way around the circuit is open and no current will flow. I presume by 'ordinary diode' you mean a diode that is not a light emitting diode (LED). A LED is just a diode that emits light when current flows through it. Its purpose is to make light. A non-LED diode doesn't emit light. Its purpose is to allow current through a circuit in only one direction. A common use for ordinary diodes is in "rectifying circuits" which convert AC to DC.There are many other uses though.
Does a diode allow electricity to flow in one direction?
Diodes come in so many different types and uses. Your statement does hold true to a certain point. They are highly valued for their diverse applications. The zener diode which is the rare exception because this semiconductor is usually reverse biased ( installed backwards) to function in the circuit. These were primarily designed to be voltage regulators available in a wide variety of voltages and types. In Engineering terms this operates in the avalanche region (reversed). All other types would run forward biased (in conduction). The anode is the positive end and the cathode negative.
Discussion of zener diode a voltage regulation?
A zener diode has a relatively flat voltage to current curve when reverse biased. Within limits, you can consider that the voltage across the zener diode is constant. You can use the zener as the primary regulator, so long as you consider the power requirements and dissipation of both the zener and the load, and you do not overload the zener. More often, the zener is used as a voltage reference in a larger power supply that uses other components, linear or switched, to supply the load.
What property of addition uses parantheses?
There is no property of addition that uses parentheses.
Where is a diode used?
A diode is used as a rectifier, clipper and to get square wave form. The combination of diode (bridge) is used for full wave rectification. It also used as a voltage controlar. Different types of diodes have different uses in different appliences.
What are some practical uses of diodes?
Diodes are largely used for changing AC into DC. A half wave diode bridge will use two diodes for this purpose. A full wave bridge uses four diodes to accomplish this task.See related links below.

Why does argon have the uses of what its used for?
Its inert property makes it suitable for its uses.
What are the functions and the uses of the diode?
A diode conducts in only one direction. Use this to rectify AC to absorb inductive kick from relay coils- protecting output transistors from inverse voltage. as simple logic elements OR, AND, etc.
What diode equation?
It is an equation that describes the I-V characteristic of a diode. In other words, how the current depends on the voltage.The Shockley diode equation uses an exponential expression. See the Wikipedia article on "Shockley diode equation" for more details. However, for many practical purposes, it's accurate enough to think of a diode as being "open" in the "forward" direction (no voltage drop), and having a voltage drop of about 0.7 V (in the case of diodes made from silicon) in the "reverse" direction.
