Charging

Front

What happens to a plastic strip when it is rubbed with cotton?

Back

The plastic strip loses electrons to the cotton and becomes positively charged.

Front

What is a conductor?

Back

A material through which electrons move easily.

Front

What is an insulator?

Back

A material that does not allow electrons to move easily.

Front

What is grounding?

Back

Removing a static charge by providing a path to the ground.

Front

What happens when two like-charged balloons are brought near each other?

Back

The balloons will repel each other.

Front

What is static electricity?

Back

A stationary electric charge typically produced by friction.

Front

What is the role of electrons in charging?

Back

Electrons are negatively charged particles that can be transferred between materials.

Front

What is the difference between charging by friction and charging by induction?

Back

Charging by friction involves direct contact and transfer of electrons, while charging by induction involves rearranging charges without direct contact.

Front

What is the significance of a metal doorknob in discharging static electricity?

Back

A metal doorknob provides a conductive path to the ground, allowing static charge to dissipate.

Front

What is the principle of conservation of charge?

Back

The total electric charge in an isolated system remains constant.
