Electrical Circuits

Front

What is an electrical circuit?

Back

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

Front

What are the two main types of circuits?

Back

The two main types of circuits are series circuits and parallel circuits.

Front

What happens in a series circuit when one component fails?

Back

In a series circuit, if one component fails, the entire circuit stops working because the current cannot flow.

Front

What happens in a parallel circuit when one component fails?

Back

In a parallel circuit, if one component fails, the other components can still operate because they have separate paths for current.

Front

What is the role of a battery in a circuit?

Back

A battery provides the electrical energy needed to push the current through the circuit.

Front

What is a complete circuit?

Back

A complete circuit is one that has no breaks, allowing current to flow uninterrupted.

Front

What is an incomplete circuit?

Back

An incomplete circuit has a break or gap that prevents current from flowing.

Front

What is the function of a switch in a circuit?

Back

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

Front

What is light refraction?

Back

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

What is the difference between reflection and refraction?

Back

Reflection is when light bounces off a surface, while refraction is when light bends as it passes through a medium.
