Electric Charges Quiz

What is electric charge?

• A type of battery

• The flow of water through a pipe

• The color of an object

• A physical property of matter

Name two examples of conductors and two examples of insulators.

• Conductors: Paper, Fabric; Insulators: Aluminum, Nickel

• Conductors: Iron, Steel; Insulators: Copper, Brass

• Conductors: Copper, Aluminum; Insulators: Rubber, Glass

• Conductors: Wood, Plastic; Insulators: Silver, Gold

What are the two types of electric charge? Explain with examples.

• Positive and negative

• North and south

• Left and right

• Up and down

Describe the activity when a balloon is rubbed against hair and then brought near small pieces of paper.

• The small pieces of paper are attracted to the hair.

• The small pieces of paper are unaffected by the balloon.

• The small pieces of paper are repelled by the balloon.

• The small pieces of paper are attracted to the balloon.

Explain the terms repel and attraction in the context of electric charges.

• Opposite charges have no effect, like charges attract

• Opposite charges attract, like charges repel

• Opposite charges repel, like charges attract

• Opposite charges attract, like charges have no effect

What happens when two objects with the same type of charge are brought close to each other?

• They will repel each other

• They will merge into one object

• They will attract each other

• They will remain stationary

How does the concept of electric charges apply in everyday life?

• Electronic devices and household appliances

• Automobile maintenance and repair

• Cooking techniques and recipes

• Gardening tools and equipment

What are the safety precautions to be taken while working with electric charges?

• Wearing insulated gloves, using insulated tools, working in dry conditions, and turning off power before working on electrical equipment.

• Working alone with no one nearby to help in case of an emergency

• Using wet tools and equipment

• Wearing metal jewelry while working with electric charges

Describe an experiment to demonstrate the transfer of electric charges.

• Connect a light bulb to a power source and observe the light to demonstrate the transfer of electric charges.

• Rub a balloon against a piece of fabric to create static electricity, then bring the balloon close to small pieces of paper or hair to observe the transfer of electric charges.

• Rub two pieces of fabric together to create static electricity, then touch the fabric to a metal object to transfer the electric charges.

• Place a battery in water and observe the movement of the water molecules to demonstrate the transfer of electric charges.

Explain the concept of static electricity and provide an example of its application in everyday life.

• Static electricity is the build-up of electric charge on the surface of objects. An example of its application in everyday life is the use of static electricity in photocopiers and laser printers to attract and transfer toner to paper.

• Static electricity is the flow of electric charge through a conductor. An example of its application in everyday life is the use of static electricity in cooking techniques to generate heat for cooking food.

• Static electricity is the color of an object. An example of its application in everyday life is the use of static electricity in gardening tools and equipment to enhance plant growth.

• Static electricity is a type of battery. An example of its application in everyday life is the use of static electricity in automobile maintenance and repair to power vehicle engines.
