WHAT IS AN ELECTRIC CIRCUIT?

An electric circuit is a path in which electrons from a voltage or current source flow. Electric current flows in a closed path calledan electric circuit. The point where those electrons enter an electrical circuit is calledthe "source" of electrons.

WHAT IS NEEDED TO MAKE A COMPLETE CIRCUIT?

A simple circuit requires three (3) things: A source of electrical

potential difference or voltage. (Typically a battery or electrical outlet) A conductive path which would allow for the movement of charges. Many a times you might have thought of making your own flashlight, but dropped the idea of doing it, thinking that it might be a complicated affair, then let me tell you, the instructions below spell everything out for you……Just be careful and have fun!!

SUPPLIES YOU NEED:

Wires, LED, Battery Holder Battery Snap Cable Tie On – Off Switch Plastic Box, 1.5V battery2 Nos. (not includedin kit).

Take a Plastic Box and position the LED in the hole in the center ofthe box. Place the On – off Switch in the hole given (Unscrew the On – Off Switch, then place in the hole and affix it with the help of nut.)

Position Battery Holder in the plastic box and affix it at the base of box with the help of CableTie.

Take a batter ysnap and secure one of the end with the On – Off

Switch and free terminal with the LED. Take wire and secure it to the On – Off Switch and free terminalwith the LED.

Affix your batteries with the Battery Holder. Switch on and Light up your flashlight. If your flashlight didn’t work, verify the connections.

HOW DOES A SWITCH WORK?

Switches are like gates that control the flow of electricity in a circuit.When a switch is open, it creates a gap in the circuit and current will not flow. When it is closed, it completes the circuit, and current flows through it. Switches are used in parallel circuits to turn different parts of the circuit on and off.
