Electric Charge and Static Electricity

Front

What is electric charge?

Back

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

Front

What happens when an object has equal numbers of positive and negative charges?

Back

The object is electrically neutral or has no charge.

Front

What is static electricity?

Back

Static electricity is the accumulation of electric charge on the surface of objects, which can cause them to attract or repel each other.

Front

What is the principle of attraction in electric charges?

Back

Opposite charges attract each other, meaning a positive charge will attract a negative charge.

Front

What is the principle of repulsion in electric charges?

Back

Like charges repel each other, meaning two positive charges or two negative charges will push away from each other.

Front

What is an example of static electricity in everyday life?

Back

An example is when you rub a balloon on your hair and it sticks to the wall due to static charge.

Front

What are conductors?

Back

Conductors are materials that allow electric charges to flow freely, such as metals.

Front

What are insulators?

Back

Insulators are materials that do not allow electric charges to flow freely, such as rubber or glass.

Front

What is grounding?

Back

Grounding is the process of transferring excess charge to the Earth, which can prevent the buildup of static electricity.

Front

What is the law of conservation of charge?

Back

The law states that the total electric charge in an isolated system remains constant; charge can neither be created nor destroyed.
