Transfer of Energy

Front

What are insulators?

Back

Materials that do not allow electricity and heat to flow through them, such as wood, plastic, air, and rubber.

Front

What type of energy travels through space and moves in waves?

Back

Light energy.

Front

What is a parallel circuit?

Back

A type of electrical circuit where there are multiple paths for current to flow.

Front

What type of energy is produced when a radio is plugged in?

Back

Sound energy, which is produced when electric energy is converted.

Front

What process does the sun use to heat the Earth?

Back

Radiation, which is the transfer of energy through space.

Front

What is conduction?

Back

The transfer of heat through direct contact between materials.

Front

What is convection?

Back

The transfer of heat through the movement of fluids (liquids or gases).

Front

What is the difference between conductors and insulators?

Back

Conductors allow electricity and heat to flow through them, while insulators do not.

Front

What is the formula for calculating electrical power?

Back

Power (P) = Voltage (V) x Current (I).

Front

What is the role of a resistor in a circuit?

Back

To limit the flow of electric current.
