Front

What is a semiconductor?

Back

Materials which can conduct electricity better than insulators but not as well as conductors, commonly used in electronics.

Front

What device is used to detect electric charges?

Back

Electroscope.

Front

If the magnitude of charge on q2 doubles, what happens to the force of interaction between two charged particles?

Back

The force of interaction would double, resulting in 4.8 N.

Front

What happens when two like charges interact?

Back

They repel each other.

Front

How does a balloon acquire a charge when rubbed on clothes?

Back

By friction.

Front

What is the definition of an insulator?

Back

Materials that do not allow electric charges to flow freely.

Front

What is the principle of charge conservation?

Back

The total electric charge in an isolated system remains constant.

Front

What is the difference between conductors and insulators?

Back

Conductors allow electric charges to flow easily, while insulators do not.

Front

What is an example of a good conductor?

Back

Copper.

Front

What is an example of a good insulator?

Back

Rubber.
