Energy and Engineering Review

Front

What is an electric circuit?

Back

An electric circuit is a closed loop that allows electric current to flow, typically consisting of a power source, wires, and a load (like a light bulb).

Front

What happens when you connect batteries in series?

Back

Connecting batteries in series increases the total voltage of the circuit, allowing more current to flow.

What is the role of a switch in an electric circuit?

Back

A switch controls the flow of electricity in a circuit, allowing it to be turned on or off.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter, which is related to the motion of particles.

Front

How does light travel?

Back

Light travels in straight lines until it hits an object or surface.

Front

What is reflection of light?

Back

Reflection of light is when light bounces off a surface, changing direction.

Front

What is refraction of light?

Back

Refraction of light is the bending of light as it passes from one medium to another, like from air to water.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of circuit where there are multiple paths for electricity to flow, so if one path is broken, others can still work.

Front

What is a series circuit?

Back

A series circuit is a type of circuit where all components are connected in a single path, so if one component fails, the entire circuit stops working.

Front

What is electrical energy?

Back

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