What is an electric circuit?

Back

An electric circuit is a closed path through which electric current flows, allowing devices like bulbs to operate.

Front

What is a conductor?

Back

A conductor is a material that allows electricity to flow through it easily, such as metals like aluminum and copper.

Front

What is an insulator?

Back

An insulator is a material that does not allow electricity to flow through it easily, such as rubber or plastic.

What happens in a series circuit when one component fails?

Back

If one component in a series circuit fails (like a bulb burning out), the entire circuit is broken and all components stop working.

Front

What is the role of a battery in a circuit?

Back

A battery provides the electrical energy needed to power the circuit.

Front

What is the purpose of a switch in a circuit?

Back

A switch is used to open or close a circuit, controlling the flow of electricity.

Front

What is the difference between a series circuit and a parallel circuit?

Back

In a series circuit, components are connected one after another, while in a parallel circuit, components are connected across common points, allowing multiple paths for current.

Front

What materials are good conductors of electricity?

Back

Good conductors include metals like copper, aluminum, and silver.

Front

What materials are considered insulators?

Back

Insulators include rubber, glass, plastic, and wood.

What is the effect of adding more bulbs in a series circuit?

Back

Adding more bulbs in a series circuit decreases the brightness of each bulb because the total voltage is divided among them.
