What does an led do in an electronic circuit?
the function of an led is to give of light coming through an electrical circuit
Which way does LED go in a circuit?
series
What happens to an LED When the voltage is to high?
when a LED is subjected to a high voltage it will heat up and burn the internal junction, which will leave the LED open circuit.
What the role of a resistor in an led circuit?
a resister is to RESIST current flow....if the LED gets the full effect of the power supply, the LED will immediately blow out.
Can you suggest more efficient led driver circuit?
We probably can. You would need to provide the original circuit first, though. :D
Components used to protect a LED?
The component used to protect a LED from burning up is called a resistor.
3 component of nstp and their component?
circuit board,led,buzzer
Which component can replace the infrared LED in any electronics circuit?
If a circuit requires an IR LED, it requires an IR LED, there is no replacement. If a circuit does not require an IR LED, there is no need to look for a replacement.
How is LED different from lamp?
similarity between lamp and LED- lamp in simple current is used to show that current is flowing and LED performs the same task but in electronic circuit .difference between lamp and LED-lamp in simple current is used to show that current is flowing and LED performs the same task more efficiently but in electronic circuit . so LED works more efficiently in electronic circuit than lamp which performs task in simple circuit.
How LED flashing circuit board function?
It may work in several different ways, depending on the actual circuit used. As asked no better answer can be given than the circuit board alternately turns the current in the LED on and off.
What does an led do in an electronic circuit?
the function of an led is to give of light coming through an electrical circuit
Can bulbs be used in the same circuit with LED's?
If your reference to bulbs is light bulbs then yes they can be mixed. The led lamps have to be ballasted to use them in home lighting.
What is the difference between LDR and LED?
An LED is an electircal component which converts electrical energy into light energy whereas an LDR uses light to complete the circuit and maintain the flow of current.
Why light emitting diodes are good?
LED (light emitting diode) is an electronic component that generates light from the electrons flowing in one direction through it, in an electron circuit, possibly as part of a circuit board. In a circuit the light emission can be a short as a nanosecond. One or more LED's can be used to make light with a minimum of electricity. Modern applications are wide spread including optical sensor activators, calculator displays and automotive tail lights. LED's have come down in price and can last for tens of thousands of hours so have become an economical replacement for other lights in some applications.
What is a componet?
Physical pieces of a computer.
Can you use buzzer instead of led in a circuit?
Sure. If you want sound when the circuit is energized, use a buzzer. If you want a visual indication when the circuit is energized, use an LED.
What type of electronic component is an led?
It is considered a diode, a Light Emitting Diode (LED).
