What is a circuit?

Back

A circuit is a closed loop that allows electricity to flow from a power source to a load and back to the source.

Front

What is the difference between an open and closed switch?

Back

A closed switch allows electricity to flow through the circuit, while an open switch interrupts the flow of electricity.

Front

What is an electrical insulator?

Back

An electrical insulator is a material that does not allow electricity to pass through it.

Front

What is an electrical conductor?

Back

An electrical conductor is a material that allows electricity to flow through it easily.

Front

What happens to the lights in a circuit when switches are closed?

Back

When switches are closed, the circuit is complete, and electricity can flow, turning on the lights connected to that circuit.

Front

What forms of energy are produced when a circuit is closed?

Back

When a circuit is closed, it can produce light energy, sound energy, and electrical energy.

Front

What is the role of a power source in a circuit?

Back

The power source provides the electrical energy needed to drive the 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

How does resistance affect current in a circuit?

Back

Resistance opposes the flow of current; higher resistance results in lower current for a given voltage.
