Static Electricity Basics

Click on the flashcard to see the answer

What is static electricity?

Static electricity is the buildup of electrical charges on the surface of materials.

How does static electricity differ from current electricity?

Static electricity is stationary while current electricity flows through a conductor.

What causes static electricity?

Static electricity is caused by an imbalance of electric charges.

Why does rubbing a balloon on your hair create static electricity?

Rubbing causes electrons to transfer from hair to the balloon.

What is an example of a natural occurrence of static electricity?

Lightning is a natural example of static electricity.

How can static electricity be dangerous?

Static electricity can cause sparks that might ignite flammable gases or dust.

What device is used to detect static electricity?

An electroscope is used to detect static electricity.

What role do electrons play in static electricity?

Electrons transfer between objects, creating a charge imbalance.

How can you reduce static electricity in your home?

Increase humidity and use anti-static sprays or materials.

Why do you sometimes get a shock when touching metal in winter?

Dry air enhances static electricity, causing a shock when discharged.

Can static electricity power devices?

No, static electricity cannot power devices as it doesn’t flow.

What is meant by 'static discharge'?

Static discharge happens when electric charges move to neutralize.

Why is static electricity more noticeable in dry conditions?

Dry air allows charges to build up more easily, enhancing static effects.

What is conductivity's role in static electricity?

Conductivity determines how easily charges can disperse or flow.

What happens when static electricity is discharged?

A spark or shock occurs as charges move to balance.
