Energy and Circuits

What is light energy?

• Light energy is the energy that is visible to the human eye and is produced by sources like the sun or light bulbs.

• Light energy is a form of energy that cannot be seen and is produced by chemical reactions.

• Light energy is the energy stored in the bonds of molecules and is released during combustion.

• Light energy is the energy that is only produced by artificial sources like lasers.

What is an insulator?

• A material that allows electricity to pass through easily.

• A material that does not allow electricity or heat to pass through it easily.

• A type of conductor that enhances electrical flow.

• A device used to measure electrical resistance.

What is thermal energy?

• Thermal energy is the energy that comes from the temperature of matter.

• Thermal energy is the energy stored in chemical bonds.

• Thermal energy is the energy associated with the motion of electrons.

• Thermal energy is the energy released during nuclear reactions.

What is a closed circuit?

• A circuit that is open and does not allow current to flow.

• A complete electrical loop that allows current to flow.

• A circuit that only works with batteries.

• A circuit that has multiple paths for current to flow.

What happens in a parallel circuit?

• In a parallel circuit, components are connected across common points, allowing multiple paths for current to flow.

• In a parallel circuit, all components are connected in a single path, so the current has only one route to follow.

• In a parallel circuit, the total resistance is equal to the sum of the individual resistances of the components.

• In a parallel circuit, the voltage across each component is the same, but the current can vary.

What is the difference between conductors and insulators?

• Conductors allow electricity to flow easily, while insulators do not.

• Insulators allow electricity to flow easily, while conductors do not.

• Both conductors and insulators allow electricity to flow easily.

• Conductors and insulators are the same in terms of electrical conductivity.

What is energy transfer?

• The process of moving energy from one place to another or changing it from one form to another.

• A method of storing energy for future use.

• The ability to create energy from nothing.

• A technique to measure energy consumption.

What is kinetic energy?

• Kinetic energy is the energy of motion.

• Kinetic energy is the energy stored in an object at rest.

• Kinetic energy is the energy of an object due to its temperature.

• Kinetic energy is the energy released during a chemical reaction.
