Front

What is a circuit?

Back

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

Front

What is the difference between a series circuit and a parallel circuit?

Back

In a series circuit, components are connected end-to-end, so the current flows through each component one after another. In a parallel circuit, components are connected across common points, allowing multiple paths for the current.

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 complete the loop.

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 function because there are multiple paths for the current to flow.

Front

What is resistance in a circuit?

Back

Resistance is a measure of how much a component opposes the flow of electric current, often caused by materials that do not conduct electricity well.

Front

What is current?

Back

Current is the flow of electric charge through a conductor, measured in amperes (A).

Front

What is voltage?

Back

Voltage is the electric potential difference between two points in a circuit, which drives the flow of current, measured in volts (V).

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 resists the flow of electric current, preventing it from passing through, such as rubber or glass.

Front

What is a power source in a circuit?

Back

A power source provides the energy needed to drive the current through the circuit, such as a battery or power outlet.
