Step 3 Attach one jumper with the positive terminal of LED and other
jumper with the resistor.

Step 4 Connect the battery. Attach the positive terminal of the battery

to the LED, and the negative terminal to the resistor.
Step 5 Observe the result.

Output

When we connect all the parts together, the LED light will turn on. The power

from the battery travels through the jumper wires and resistor, reaching
the LED, which makes it glow. If everything is connected correctly, the

LED will light up and stay on. But if something isn’t connected properly,
the light won’t turn on.

Application
This circuit can be used to create a

portable reading light. It allows users to
make a small, battery-powered LED lamp

that can be used in dark places, like under
the covers or during a camping trip.
