Front

What measures the speed/amount of the current in a circuit?

Back

Ammeter

Front

Which type of circuit will have the brightest lamp?

Back

A circuit with lower resistance and higher voltage.

Front

What type of circuit do security alarms use?

Back

Series circuits, because they turn on when the circuit is broken.

A power source that provides electrical energy.

Front

What is the role of a switch in a circuit?

Back

To open or close the circuit, controlling the flow of electricity.

Front

What is resistance in a circuit?

Back

The opposition to the flow of electric current, measured in ohms.

Front

What is voltage?

Back

The electric potential difference between two points, measured in volts.

Front

What is a parallel circuit?

Back

A circuit where components are connected across common points, allowing multiple paths for current.

Front

What happens in a series circuit if one component fails?

Back

The entire circuit is broken and all components stop working.
