The document provides an introduction to electricity and circuits for class 6 science, explaining the components of a circuit, including cells, switches, bulbs, and connecting wires. It distinguishes between open and closed circuits, highlighting that a closed circuit allows current flow and illumination, while an open circuit does not. Additionally, it outlines essential safety precautions to follow when using electrical appliances to prevent accidents and injuries.

Electricity and Circuits – Class 6, Science
1. Define a circuit. Draw the labeled diagram and its different components.
Ans. A circuit is a path along which an electric current passes. It consists of
several different electrical components, which are listed below:
 There is a cell or a battery in the circuit used as a source of electric current.
 There is an electric switch used to regulate the flow of current. It is also called the
‘key.’ The current flows in the circuit when the switch is ‘on,’ and it does not flow
when the switch is ‘off.’ A bulb is connected to the circuit to confirm the current
flow. The circuit is complete when it lights up, indicating that the current flows.
 On the other hand, when the bulb does not glow, the circuit is said to be
incomplete, i.e., the current is not flowing.
 An essential component of the circuit is the connecting wire, which connects all the
circuit components to make the current flow.
2. Discuss open and closed circuits with the help of diagrams.
Ans. A circuit gets called closed when it is complete in every way, meaning that
its connections are intact. The current passes through it after turning it on, and
the bulb illuminates.

When connections are not intact, i.e., broken, a circuit is considered open or not
complete. The bulb does not light up when the switch gets turned on in an open
circuit. It indicates that there is no current flowing in the circuit. It may get
caused by damaged wires or a circuit with improperly connected components.

3. Discuss various protection precautions and procedures when electrical
appliances are in use.
Ans. Electricity is beneficial to humans. It has improved the quality of our lives by
making them more enjoyable, luxurious, and convenient. On the other hand, it
can be just as dangerous. It can result in serious accidents, injuries, and even

death. As a result, it is advisable to take the following precautions and safety
measures when using electrical appliances:
1. Never touch electrical switches or gadgets when any body part is moist.
2. Wear rubber hand gloves and stand on a dry wooden or plastic platform if any
repair work on any electrical items needs to get done.
3. Playing with electrical sockets or cables is never a good idea.
4. In the event of a short circuit or a spark in a switch, use a plastic or wooden stick to
turn off the main switch quickly.
5. Never use water to put out a fire caused by electric lines. Turn off the power, then
extinguish the fire using dry sand.
Now that we know so much about electricity and circuits, let’s test our
knowledge by answering a few quick questions.
