Understanding Electrical Energy

What are some examples of how electrical energy is used in everyday life?

• Powering lights and appliances

• Growing plants without water

• Creating natural disasters

• Stopping the flow of water

How does electrical energy transform into different types of energy?

• It stays the same and does not change

• It can turn into heat, light, sound, and motion

• It can only be used for lighting

• It disappears when used

Why is electrical energy important for modern technology?

• It helps power devices such as computers, phones, and machines

• It has no role in modern technology

• It prevents technology from working

• It only works with natural materials

What is the difference between static electricity and electric current?

• Static electricity flows continuously, while electric current stays in one place

• Static electricity is a buildup of charges, while electric current is a continuous flow

• Electric current is weaker than static electricity

• They are both the same

Which of the following is an example of static electricity?

• Turning on a television

• Rubbing a balloon on your hair and making it stick to a wall

• Using a microwave

• Plugging in a refrigerator

How does electric current help power devices in your home?

• It stores energy without letting it flow

• It allows charged particles to build up in one place

• It provides a continuous flow of energy to devices

• It removes energy from devices
