A: Add the proper resistor in series with the LED. What resistor? Simple 10volts source minus the LED source divided by the 20ma current that should be flowing gives you the resistor 10-1.8=8.2/.02=900 ohms. The 1.8 can be anything it is up to the LED voltage drop. LONG LEAD IS POSITIVE SHORT IS NEGATIVE SINCE IT IS A DIODE

When a pencil led connect to a circuit whether the bulb glow?
Yes it will - graphite is a conductor.

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 LED do in a circuit?
light up when forward biased
What is the function of the resistor in an led circuit?
current limiter.
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.
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.
When a pencil led connect to a circuit whether the bulb glow?
Yes it will - graphite is a conductor.

How do you wire mood lighting into a car?
Mood lighting in the car can be done by connecting LED lights to the rest of the battery circuit. Disconnect the negative cable and connect the LED light connector to the circuit that leads to the rear lights.

How do you connect a volt to a circuit?
A volt can not be connected to a circuit.
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 connect a variable resistor to circuit?
To connect a variable resistor to a circuit, identify the two terminals of the variable resistor. Connect one terminal to the input or output of the circuit where you want to adjust the resistance. Connect the other terminal to either the ground or another reference point depending on the circuit's design. Ensure that the resistance value on the variable resistor is adjusted as needed for your circuit application.
How do you connect a ammeter into a circuit?
connect ammeter in series with load.
What does an led do in an electronic circuit?
the function of an led is to give of light coming through an electrical circuit
How is an ammeter connected in a circuit?
Series connect it within the line of the circuit for which you are interested in measuring the current flow.More detailSince we measure the flow of current IN the circuit, the ammeter must be connected in series with the part of the circuit for which you are interested in measuring the current flow.One of the ammeter's terminals must be connected to a point of the incoming current flow and its second terminal must be connected to the point of on-going current flow. To do this, cut the relevant circuit wire and connect one terminal of the ammeter to each end of the cut.
