Question

Give an activity to design a simple electric circuit with a switch.

Accepted Answer

Aim: To make a simple electric circuit.

Materials required: Electrical wires, electric cell, small torch bulb, insulation or electric tape, a pair of scissors or blade.

Procedure:

Cut the wire into two pieces.

Expose the ends of the two wires using scissors or blade so that the metal part of the wires is visible.

Take one of the two wires and attach this to the positive terminal of the cell (the terminal that is marked with a '+' sign).

Attach the other end of this wire to one of the terminals of your torch bulb.

Take another wire and attach this to the negative terminal of the electric cell. Keep the other end of this wire free.

Your circuit is now ready. Observe what happens when you make the free end of the second wire touch the other terminal of the torch bulb.

Observation: When the free end of the wire touches the second terminal of the torch bulb, the bulb glows.

Precautions:

Adult supervision is necessary.

Do not use any source of electricity for this experiment other than a pencil cell.
