LED Table Or Reading Lamp Circuit

Working Explanation:

In this circuit, we used 20 bright LEDs and 20 resistors of 20 ohms. From the circuit, it is easily visible that we connected 20 LEDs in a parallel circuit. We used 3 cells of 1.5 V for this circuit will work on a power supply of 4.5 V. Each LED is connected to a 20 Ohm resistor.

Applications and Uses:

  • It can be used as a Bedside lamp and table lamp.
  • It can also be used as a keyboard lamp to view the keys of the keyboard.
  • It can also be used as an emergency lamp in the absence of an AC power supply.
