### CLASS RESPONSE

#### 1. Name any five appliances used at home that work with electricity.

ANSWER: Fans, refrigerator, heater, washing machine and Television are five appliances used at home that work with electricity.

#### 2. What are insulators? Give two examples.

ANSWER: Insulators are the materials that do not allow electric current to pass through them. Examples: rubber and wood.

#### 3. How does a bulb get fused?

ANSWER: Bulb get fused because of the breakage in its filament (thin wire that provides support to bulb). Breakage in filament results in break in the path of the electric current between two terminals.

#### 4. What is the source of electricity in an electric torch?

ANSWER: Battery is the source of electricity in an electric torch. Two or more cells connected end to end is called battery.

#### 5. Name the device used for completing and breaking the circuit.

ANSWER: Switch is used for completing and breaking the circuit.

#### 6. Does the current flow in the circuit , if the key is closed?

ANSWER: Yes the current will flow in the circuit, if the key is closed because closed key results in switch on.

#### 1. Name any two gadgets that use electric cell for their working.

ANSWER: Wrist watches and TV remote.

#### 2. What is an electric circuit?

ANSWER: The path along which electric current flows is called electric circuit.

#### 3. In which direction does the electric current flow?

ANSWER: Electric current flows from positive to negative terminal.

#### 1. Why we should not operate electrical switches with wet hands?

ANSWER: We should not operate electrical switches with wet hands because water is good conductor of electricity ( conductors) Thus, wet hands allows electric current to pass through it and we may get an electric shock.

#### 2. What is meant by open circuit.

ANSWER: When the circuit is incomplete and electric current does not flow through it. This is known as open circuit.

#### 3. Define insulators.

ANSWER: Insulators are the materials that do not allow electric current to pass through them. Examples: rubber and wood.

#### 4. Sahil’s hands are wet, but still goes to switch on the fan. Monika immediately stops him from doing so.

##### (a) Why does Monika stop Sahil?

ANSWER: Monika stop Sahil because water is good conductor of electricity. Thus, wet hands allows electric current to pass through it and we may get an electric shock.

#### 5. What happens when the switch is in the (a) ‘ON’ position (b) ‘OFF’ position

ANSWER: When the switch is on then the circuit is open and thus allows electric current to pass through it. When the switch is off then the circuit is closed and thus do not allow electric current to pass through it.

#### 1. Draw a labelled diagram of an electric bulb. Explain its parts.

ANSWER: #### 2. Differentiate between conductors and insulators. Give one example of each. #### 3. How does electricity flow in a circuit? Draw an open circuit.

ANSWER: Electricity flow in a circuit when the switch (or key) is opened. It results in complete electric circuit and thus current is allowed to flow through the circuit.

#### 4. (a) Name the source of electricity in a torch.

ANSWER: Electric cells are the source of electricity in a torch.

#### (b) Draw a labelled diagram of its inner view.

ANSWER: ### HOTS (Higher Order Thinking Skills)

#### 1. What alternative devices can we use if there is sudden breakdown in electric supply?

ANSWER: Electric generator, invertor etc. are the alternative devices that can be used if there is sudden breakdown in electric supply.

#### 2. Give reasons for the following:

##### (a) We remove the plastic coating from ends of an electric wire while using it for connections in an electric circuit.

ANSWER: We remove plastic coating from from ends of an electric wire because plastic is bad conductor of electricity that do not allow current to flow through the circuit. Plastic is used at the ends of the wire so that we do not get electric shock.

##### (b) The handles of tools, like screwdrivers and pilers, usually have plastic or rubber covers on them.

ANSWER: The handle have plastic or rubber covers as they are bad conductor of electricity that do not allow current to flow through them and thus save us from electric shock.

#### 3. Can electricity make the bulb glow in figure (a)

ANSWER: No, as it is not connected to circuit.

#### 4. If a person gets caught by the current, why are we advised not to touch the person directly rather to touch him with a wooden material like stick?

ANSWER: Because wood is bad conductor of electricity that does not allow current to pass throgh them and thus prevents us from an electric shock.
