S5P2a (static vs current electricity)

Front

What is current electricity?

Back

Current electricity is the flow of electric charge through a conductor, such as a wire, and is used to power devices in homes and industries.

Front

What is static electricity?

Back

Static electricity is the buildup of electric charge on the surface of objects, which can cause sparks or shocks when discharged.

Front

Give an example of a source of human-harnessed current electricity.

Back

A hydroelectric dam is an example of a source of human-harnessed current electricity.

Front

Which of the following is NOT an example of human-harnessed electricity? Lightning, Windmill, Lamp, or Hydroelectric dam?

Back

Lightning is NOT an example of human-harnessed electricity.

Front

What is the main difference between static electricity and current electricity?

Back

Static electricity is natural energy while current electricity is human-harnessed energy.

Front

What does it mean when we say 'negative charge moving through a wire'?

Back

It refers to current electricity, where electrons (negative charges) flow through a conductor.

Front

How does static electricity differ from current electricity in terms of energy release?

Back

Static electricity is a quick release of energy, while current electricity flows continuously.

Front

What is an example of static electricity?

Back

An example of static electricity is getting a shock from a doorknob after walking on a carpet.

Front

What is a common effect of static electricity?

Back

A common effect of static electricity is the attraction or repulsion of objects, such as socks sticking together.

Front

What is a hydroelectric dam?

Back

A hydroelectric dam is a facility that generates electricity by using the flow of water to turn turbines.
