What does an led do in an electronic circuit?
the function of an led is to give of light coming through an electrical circuit
Should a resistor go on the positive or negative side of an LED?
It does not matter. Kirchoff's Current Law states that the signed sum of the currents entering a node is zero. A consequence of that law is that the current in every part of a series circuit is the same. The only thing that resistor location affects is the potential voltage of the LED terminals with respect to the rest of the circuit. Certainly, if you are driving the LED with high voltage, such as 120VAC, you should consider the resistor location so as to reduce electrocution hazard but, the LED's performance is not affected by resistor location in the circuit.
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
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.
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 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 does a circuit board look like?
A circuit board consists of numerous electronic components, depending on the application, these components can be in the thousands or in the ten's, therefore circuit boards vary in numerous sizes, all connected using very fine electrical connection strands.
The 4017 integrated circuit is a type of what circuit?
led to 250 watts bulb
How to build an led cIRCUIT?
Connect an LED, two AA batteries, and a resistor of around 100-150 ohms, all in series.If the LED doesn't light, then turn either the LED or the batteries around in the circuit.
What are LED legs?
It probably means LED leads, which are the two wires sticking out from the LED that connect it to the circuit.
What is a circuit that goes more than one way?
A circuit can only go two ways. They are from the beginning to the end or from the end to the beginning.
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 do you make a led chaser circuit without ics?
how many led's do you want to drive ???
What does LED do in a circuit?
light up when forward biased
What is the function of the resistor in an led circuit?
current limiter.
