Static Electricity and Charge Imbalance

Static electricity can occur unexpectedly, like when touching a doorknob after walking on a carpet. It involves the movement of electrons between atoms, leading to charge imbalance. Conductors and insulators play roles in how static electricity builds up. In nature, static electricity can cause lightning, a powerful discharge of energy.

What is the initial cause of static electricity?

• Movement of atoms

• Movement of neutrons

• Movement of protons

• Movement of electrons

Which particles in an atom are responsible for creating a charge imbalance?

• Neutrons and electrons

• Protons and atoms

• Protons and neutrons

• Electrons and protons

What happens when electrons move from one object to another?

• The first object becomes an insulator

• The first object becomes neutral

• The first object becomes positively charged

• The first object becomes negatively charged

What is the term for the quick movement of electrons that causes a spark?

• Electric flow

• Static discharge

• Charge imbalance

• Charge polarization

Which materials are likely to allow electrons to flow easily?

• Insulators like rubber

• Insulators like glass

• Conductors like metals

• Insulators like plastic

Why does static build-up occur more with insulators?

• They have tightly bound electrons

• They have loosely bound electrons

• They are electrically neutral

• They are good conductors

What happens when you touch a metal door knob after walking on a rug?

• The door knob's electrons jump to your hand

• The door knob loses electrons

• The door knob becomes an insulator

• The door knob gains protons

What natural phenomenon is an example of static electricity?

• Lightning

• Wind

• Earthquake

• Rain

What is believed to contribute to charge separation in clouds?

• Movement of air

• Circulation of water droplets and ice particles

• Sunlight

• Wind speed

Can lightning strike the same place more than once?

• No, it strikes only once

• Yes, it can strike multiple times

• Only during a storm

• It depends on the weather
