1 Basics of: Electricity and Electric Circuits

Front

What is a closed circuit?

Back

A closed circuit is a complete electrical loop that allows current to flow, enabling devices like light bulbs to operate.

Front

What is an open circuit?

Back

An open circuit is a broken electrical loop that prevents current from flowing, causing devices to not operate.

Front

What are the essential components required for a light bulb to light up?

Back

Wires, a battery, and a light bulb are required for a light bulb to light up.

Front

What happens if you replace a conductor with an insulator in a circuit?

Back

If you replace a conductor (like a paper clip) with an insulator (like a plastic spoon), the bulb will not light.

Front

What is the function 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 the role of a battery in a circuit?

Back

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

Front

What is a series circuit?

Back

A series circuit is a type of circuit where components are connected end-to-end, so the same current flows through all components.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of circuit where components are connected across common points, allowing multiple paths for current to flow.

Front

What is the purpose of circuit symbols?

Back

Circuit symbols are used in diagrams to represent electrical components, making it easier to understand and construct circuits.

Front

What does it mean when a light bulb is dim?

Back

A dim light bulb indicates that there is less current flowing through it, which can be caused by high resistance or insufficient voltage.
