TED-Ed: The science of static electricity - Anuradha Bhagwat

The video explains static electricity, starting with the basics of matter and atoms. It describes how charge imbalance occurs when electrons move between surfaces, leading to static discharge. The video differentiates between conductors and insulators, explaining how static buildup is more likely with insulators. It also covers static electricity in nature, particularly lightning, and how charge separation in clouds can lead to this phenomenon.

What are the three types of particles that make up an atom?

• Electrons, protons, and photons

• Electrons, protons, and neutrons

• Neutrons, photons, and ions

• Protons, ions, and electrons

What happens when electrons move from one object to another due to friction?

• The objects become electrically neutral

• The objects become positively charged

• The objects become magnetic

• A charge imbalance occurs

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

• Static discharge

• Magnetic flux

• Charge polarization

• Electric current

Which type of material is more likely to allow electrons to flow easily?

• Insulators like rubber

• Conductors like metals

• Non-conductors like plastic

• Insulators like glass

What natural phenomenon is caused by charge separation in clouds?

• Wind

• Lightning

• Rain

• Thunder
