It is only a LED and a light sensitive transistor in one package. The light from the LED activates the transistor so there is optical communication between the input and output but no electrical contact. This provides exceptional electrical isolation between the two circuits involved.
An application that is most common is in a switched mode power supply, or a pulse width modulated power supply, if you prefer. These are exceptionally common in almost all contemporary AC adapters for TVs, monitors and other electronic devices.

Explain construction operation of de Sauty bridge?
explain construction & operation of de sauty bridge
Why bjt is called current controlled current device?
Because the operation of the transistor is determined by the current at the base. the principle equations of BJT operation are: Ic = h*Ib ,and Ie=Ib+Ic thus device operation is controlled by the input current.
What are the Principles of operation of automatic voltage regulator?
The principles of operation of the automatic voltage regulator is that of the excitation system. The working principle is to regulate the flow of reinforcement on the exciter.

What is the actual use of moc3011?
When people build systems that automatically turn on and off light bulbs and other mains-powered devices, they typically use a microcontroller to decide when to turn things on and off. Alas, microcontrollers cannot be directly connected to mains power. So these people typically build a system to allow the microcontroller to indirectly turn on and off the light bulbs: First, the microcontroller turns on (or off) a small LED inside an optoisolator, when turns on (or off) the silicon switch inside the optoisolator, which turns on (or off) a triac. The triac acts just like a light switch, turning on (or off) the light bulbs or other mains-powered devices attached to it. The MOC3011 triac driver optoisolator is often used in such applications.
How do you make a driver circuit for an optoisolator?
All you need to do is provide enough bias current thru the diode, usually less than 20 mA. Find a datasheet and look at the bottom for recommended circuits.
inverse operation?
the opposite operation of an operation
An operation that undoes another operation?
This is called an inverse operation.
What is inverse operation?
An inverse operation undoes the effect of another operation. For example, addition is the inverse operation of subtraction, and multiplication is the inverse operation of division. Applying an operation and its inverse leaves you with the original value.
What is operation flood related to?
White revolution was associated witha) Operation River b) Operation milk c) Operation Flood d) Operation Amul
First pregnancy is operation second pregnancy is operation or normol?
Likely an operation.
What is the order of operation for 27?
There is no operation for a single number and so there can be no order of operation.
What is an additive operation?
An additive operation is an operation which produces the sum of two operands.
