What is an electric circuit?

Back

An electric circuit is a closed loop that allows electric current to flow through it, consisting of a power source, conductors, and a load.

Front

What are the main components of a circuit?

Back

The main components of a circuit are the power source (like a battery), conductors (wires), and a load (like a light bulb or motor).

Front

What is a conductor?

Back

A conductor is a material that allows electric current 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 electric current to flow through it easily, such as rubber or glass.

Front

What is a series circuit?

Back

A series circuit is a type of circuit where all components are connected in a single path, so the current flows through one component to get to the next.

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 current to flow through multiple paths.

Front

What happens if one component fails in a series circuit?

Back

If one component fails in a series circuit, the entire circuit stops working because the current cannot flow.

Front

What happens if one component fails in a parallel circuit?

Back

If one component fails in a parallel circuit, the other components can still operate because there are multiple paths for the current to flow.

Front

What is a switch in a circuit?

Back

A switch is a device that can open or close a circuit, allowing or stopping the flow of electric current.

Front

What is voltage?

Back

Voltage is the electrical potential difference between two points in a circuit, measured in volts (V).
