Electricity and Magnetism

Front

What happens to the poles when you cut a magnet in half?

Back

Both halves get a North pole and a South pole.

Front

What is a particle that carries a negative electric charge?

Back

Front

What type of current comes from a battery?

Back

Direct current (DC).

Front

What is the unit for resistance in an electrical circuit?

Back

Ohms.

Front

What stops the flow of electricity?

Back

An insulator.

Front

What is the unit of electric current?

Back

Amperes.

Front

What is the relationship between voltage, current, and resistance?

Back

Ohm's Law: V = I × R.

Front

What is the effect of increasing resistance in a circuit?

Back

It decreases the current flow.

Front

What is the function of a conductor in an electrical circuit?

Back

It allows the flow of electric current.

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.
