Electric Charge

Front

What is electric charge?

Back

Electric charge is a physical property of matter that causes it to experience a force when placed in an electromagnetic field. It can be positive or negative.

Front

What are the two types of electric charge?

Back

The two types of electric charge are positive charge and negative charge.

Front

What is the principle of conservation of charge?

Back

The principle of conservation of charge states that the total electric charge in an isolated system remains constant over time.

Front

What is frictional charging?

Back

Frictional charging occurs when two objects are rubbed together, causing electrons to be transferred from one object to another, resulting in one object becoming positively charged and the other negatively charged.

Front

What is an insulator?

Back

An insulator is a material that opposes the flow of electric current, meaning electric charges do not flow freely through it.

Front

What is a conductor?

Back

A conductor is a material that allows electric charges to flow freely, typically metals like copper and aluminum.

Front

What is induction in terms of electric charge?

Back

Induction is a method of charging an object without direct contact, where a charged object induces a charge in a nearby neutral object.

Front

What is conduction in terms of electric charge?

Back

Conduction is the process of charging an object by direct contact with another charged object, allowing electrons to transfer between them.

Front

What is grounding?

Back

Grounding is the process of connecting an electrical circuit to the ground, allowing excess charge to be safely dissipated.

Front

What happens to an object that loses electrons?

Back

An object that loses electrons becomes positively charged.
