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.
How do you make a circuit so the lights can be turned on and off separatley?
To design a circuit so that lights can be turned on and off separately, we connect the circuit in parallel.
What does LED do in a circuit?
light up when forward biased
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.
What is the resistance value if you connect the 3 volts led at 220 volts?
Actually, if you connect the above described LED to 220 V, it will immediately burn out then the circuit will be "open" and the resistance will be "infinite".
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 do you connect a ammeter into a circuit?
connect ammeter in series with load.
Should you connect both ends of a battery in a circuit?
it is necessary to connect both the terminals of a battery to a circuit for current to flow through it..!!
