Electrical and Heat Energy

Front

What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons through a conductor.

Front

What is heat energy?

Back

Heat energy, or thermal energy, is the energy that comes from the temperature of matter. It is the energy of moving particles.

Front

What is a circuit?

Back

A circuit is a closed path through which electric current flows.

Front

What is a closed circuit?

Back

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

Front

What is an open circuit?

Back

An open circuit is a broken path that prevents current from flowing.

Front

What is a conductor?

Back

A conductor is a material that allows electrons to flow easily, such as copper.

Front

What is an insulator?

Back

An insulator is a material that does not allow electrons to flow easily, such as rubber.

Front

What is a resistor?

Back

A resistor is a device that resists the flow of electric current, creating heat.

Front

What happens when a switch is open?

Back

When a switch is open, the circuit is broken, and current cannot flow.

Front

What happens when a switch is closed?

Back

When a switch is closed, the circuit is complete, and current can flow.
