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.
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.
To build a simple circuit, you need a power source (such as a battery), a conducting material (like wires or conductive tape), and a load component (such as an LED). Connecting these elements in a closed loop allows the flow of electricity and for the circuit to function.
I have never heard of an electrical term "build" in an electrical circuit.
the function of an led is to give of light coming through an electrical 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.
led to 250 watts bulb
The lighting of the LED indicates that there is an electric current flowing through the circuit and that the LED is functioning properly. It shows that the circuit is complete and the components are properly connected to allow for the illumination of the LED.
I bought: reed switch LED Buzzer Button (On/Off) Resistor (if necessary) I connected: <---Button------Reed switch------Resistor (if necessary)------LED------Buzzer---Batteries--->
It probably means LED leads, which are the two wires sticking out from the LED that connect it to the circuit.
series
The things needed to build a circuit are:Circuit elements like resistor capacitors, inductors etcConnectors (cables)A source
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.
