Electricity and Magnetism

Front

What is a conductor?

Back

A material that easily allows electricity to flow through it.

Front

What is an insulator?

Back

A material that does not allow electricity to flow through it.

Front

What is the charge of an electron?

Back

Negative.

Front

What happens when a positively charged rod is brought near a neutral pith ball?

Back

The pith ball moves toward the rod.

Front

What surrounds every magnet?

Back

A magnetic field.

Front

What is static electricity?

Back

A stationary electric charge that is typically produced by friction.

Front

What is Ohm's Law?

Back

The relationship between voltage (V), current (I), and resistance (R) in a circuit: V = I × R.

Front

What is a magnetic field?

Back

A region around a magnet where magnetic forces can be detected.

Front

What is the difference between AC and DC current?

Back

AC (Alternating Current) changes direction periodically, while DC (Direct Current) flows in one direction.

Front

What is electromagnetic induction?

Back

The process of generating electric current from a changing magnetic field.
