PS electricity and magnetism

Front

What is required for the flow of electricity?

Back

A complete path.

Front

Why can iron, cobalt, and nickel be made into magnets?

Back

Because they have more unpaired electrons.

Front

What happens to current if voltage stays the same and resistance is increased?

Back

Current will decrease.

Front

What size resistor is needed to produce a 3 Amp current flow with a 12 Volt battery?

Back

4 Ohms.

Front

What type of circuit has components connected in a single path?

Back

Series circuit.

Front

What is the unit of electrical resistance?

Back

Ohm.

Front

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

Back

Ohm's Law: V = I × R.

Front

What is a parallel circuit?

Back

A circuit where components are connected across common points, providing multiple paths for current.

Front

What is the effect of increasing voltage in a circuit with constant resistance?

Back

Current will increase.

Front

What is magnetism?

Back

A force that can attract or repel certain materials, primarily metals like iron.
