Physics A Final Review Spencer

Front

What are insulators?

Back

Materials that do NOT allow electrons to pass through them easily.

Front

Which of the following is NOT an example of an insulator?

Back

A metal tube.

Front

What happens to objects with opposite charges?

Back

They are attracted to each other, and the force between the objects pulls them together.

Front

What is a closed circuit?

Back

A closed circuit is one where the electrical path is complete, allowing current to flow.

Front

What is total resistance in a circuit?

Back

The total resistance is the sum of all resistances in the circuit.

Front

What is a conductor?

Back

Materials that allow electrons to pass through them easily.

Front

What is the unit of resistance?

Back

Ohm (Ω).

Front

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

Back

Ohm's Law states that V = I * R, where V is voltage, I is current, and R is resistance.

Front

What is static electricity?

Back

A stationary electric charge typically produced by friction.

Front

What is the principle of conservation of charge?

Back

The total electric charge in an isolated system remains constant.
