What is a circuit?

Back

A circuit is a closed loop that allows electricity to flow from a power source, through various components, and back to the power source.

Front

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

Back

A power source provides the electrical energy needed to drive the current through the circuit.

Front

What is a conductor?

Back

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

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 glass.

What happens when a switch in a circuit is closed?

Back

When a switch is closed, it completes the circuit, allowing electricity to flow and powering the connected devices.

Front

What happens when a switch in a circuit is open?

Back

When a switch is open, it breaks the circuit, stopping the flow of electricity and turning off the connected devices.

Front

What is the difference between series and parallel circuits?

Back

In a series circuit, all components are connected in a single path, so if one fails, the entire circuit stops working. In a parallel circuit, components are connected across multiple paths, so if one fails, others can still operate.

What is electricity?

Back

Electricity is the energy created by the movement of electrons.

Front

What is a short circuit?

Back

A short circuit occurs when electricity takes an unintended path, often leading to excessive current flow and potential damage.

Front

What is a resistor?

Back

A resistor is a component that limits the flow of electric current in a circuit.
