Unit 08: Electricity Practice

Front

What is static electricity?

Back

Static electricity is the buildup of electric charge on the surface of objects, often caused by friction.

Front

How can static electricity be created?

Back

Static electricity can be created by rubbing two different materials together, such as rubbing a glass rod with silk.

Front

What is an electrical conductor?

Back

An electrical conductor is a material that allows electricity to flow through it easily, such as copper.

Front

What is an electrical insulator?

Back

An electrical insulator is a material that does not allow electricity to flow through it easily, such as rubber or plastic.

Front

What happens to electrical energy in a toaster?

Back

In a toaster, electrical energy is transformed into thermal energy to heat the bread.

Front

What is a closed circuit?

Back

A closed circuit is a complete electrical loop that allows electricity to flow.

Front

What is an open circuit?

Back

An open circuit is a broken electrical loop that prevents electricity from flowing.

Front

What is the role of negatively charged particles in static electricity?

Back

Negatively charged particles can transfer between objects, causing static cling, like Styrofoam pieces sticking to a cat's fur.

Front

What is the difference between kinetic energy and potential energy?

Back

Kinetic energy is the energy of motion, while potential energy is stored energy based on an object's position.

Front

What is the function of a circuit breaker?

Back

A circuit breaker is a safety device that automatically stops the flow of electricity in a circuit when it becomes overloaded.
