S8P5 Electricity and Magnetism

Front

What happens when a balloon is brought near a sweater?

Back

The balloon and the sweater have opposite charges.

Front

How can you increase the strength of an electromagnet?

Back

By increasing the amount of current flowing through the wire.

Front

What do electric field lines indicate about two objects with charges?

Back

If object A has a negative charge and object B has a positive charge, the electric field lines will point from B to A.

Front

What is the process by which a neutral object obtains an electrical charge?

Back

Induction.

Front

In a vacuum, if a bowling ball and a feather are dropped at the same time, what will happen?

Back

Both would hit the ground at the same time.

Front

What is static electricity?

Back

Static electricity is the buildup of electric charge on the surface of objects.

Front

What is an electromagnet?

Back

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current.

Front

What is the role of a conductor in an electric circuit?

Back

A conductor allows electric current to flow through it.

Front

What is the difference between conductors and insulators?

Back

Conductors allow electricity to flow easily, while insulators resist the flow of electricity.

Front

What is the unit of electric current?

Back

The unit of electric current is the Ampere (A).
