Circuit and Electricity

Front

What is an insulator?

Back

An insulator is a material that does not allow electric charges to flow through it easily, helping to keep electric charges inside the pathway of a circuit.

Why is Styrofoam a good insulator for keeping drinks warm?

Back

Styrofoam is a good insulator because it has air pockets that reduce heat transfer, helping to keep drinks warm for a longer time.

Front

What is an open circuit?

Back

An open circuit is a circuit that is not complete, meaning there is a break in the pathway, preventing electric current from flowing.

Front

What is a closed circuit?

Back

A closed circuit is a complete circuit that allows electric current to flow through it.

Front

What is a series circuit?

Back

A series circuit is a type of circuit where components are connected in a single path, 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 or junctions, allowing multiple paths for current to flow.

Front

What happens when a switch is closed in a circuit?

Back

When a switch is closed, it completes the circuit, allowing electric current to flow and power devices like lamps.

Front

What happens when a switch is opened in a circuit?

Back

When a switch is opened, it breaks the circuit, stopping the flow of electric current.

Front

What is the role of a cell in a circuit?

Back

A cell provides the electrical energy needed to push electric charges through the circuit.

Front

What is the function of wires in a circuit?

Back

Wires provide a pathway for electric current to flow between components in a circuit.
