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
Yes it will - graphite is a conductor.

To connect meters in a circuit, it’s essential to determine whether you need to measure voltage, current, or resistance. For voltage measurements, connect the voltmeter in parallel across the component. For current measurements, connect the ammeter in series with the circuit component. Ensure the meters are rated for the circuit's voltage and current to avoid damage.
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.
To design a circuit so that lights can be turned on and off separately, we connect the circuit in parallel.
It probably means LED leads, which are the two wires sticking out from the LED that connect it to the 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.
Yes it will - graphite is a conductor.
How do you connect an ammeter to a circuit?
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.

A volt can not be connected to a 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.
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.
connect ammeter in series with load.
The legs on an LED light are commonly referred to as "pins" or "leads." These pins are used to connect the LED to a circuit, allowing it to receive electrical current. In some cases, they may also be called "terminals" or "contacts," depending on their design and application.
