Electricity

How does a lamp transform energy?

• A lamp transforms electrical energy into radiant energy (light) and thermal energy (heat).

• A lamp transforms chemical energy into mechanical energy.

• A lamp transforms kinetic energy into potential energy.

• A lamp transforms sound energy into electrical energy.

What is a circuit?

• A circuit is a closed loop that allows electricity to flow from a power source to a device and back.

• A circuit is an open path that prevents electricity from flowing.

• A circuit is a type of electrical device that stores energy.

• A circuit is a method of measuring electrical resistance.

What are conductors?

• Materials that do not allow electricity to flow

• Materials that allow electricity to flow through them easily, such as metals like copper and aluminum.

• Materials that only allow heat to pass through

• Materials that are used for insulation

What is the difference between electrical energy and thermal energy?

• Electrical energy is the energy of moving electric charges, while thermal energy is the energy of heat.

• Electrical energy is the energy stored in batteries, while thermal energy is the energy produced by friction.

• Electrical energy is the energy of static charges, while thermal energy is the energy of light.

• Electrical energy is the energy of sound waves, while thermal energy is the energy of motion.

What is radiant energy?

• Energy that travels in waves and can be seen as light, such as the light emitted by a lamp.

• Energy stored in chemical bonds of molecules.

• Energy that is produced by nuclear reactions.

• Energy that is generated by friction between surfaces.

What is mechanical energy?

• Mechanical energy is the energy associated with the motion and position of an object, often used in machines.

• Mechanical energy is the energy stored in chemical bonds of molecules.

• Mechanical energy is the energy that comes from the heat of an object.

• Mechanical energy is the energy associated with the gravitational pull of an object.

What is electricity?

• A form of energy resulting from the flow of electric charge, typically through conductors.

• A type of renewable energy source like solar or wind.

• A measure of the power consumed by electrical devices.

• A phenomenon that occurs only in batteries.

What is the role of a light bulb in an electrical circuit?

• A light bulb transforms electrical energy into radiant energy, providing light.

• A light bulb stores electrical energy for later use.

• A light bulb regulates the flow of electrical current in the circuit.

• A light bulb converts radiant energy into electrical energy.

What is a battery?

• A device that stores chemical energy and converts it into electrical energy.

• A tool used for measuring electrical current.

• A type of renewable energy source.

• A component that increases electrical resistance.

What is static electricity?

• A type of electricity that flows continuously in a circuit.

• The buildup of electric charge on the surface of objects, often resulting in a shock when discharged.

• Electricity that is generated by moving water.

• A phenomenon that occurs only in wet conditions.
