Front

What is a circuit?

Back

A circuit is a closed loop that allows electricity to flow from a power source to devices like lights or motors.

Front

What is a closed switch?

Back

A closed switch allows electricity to flow through the circuit, turning on the connected devices.

Front

What is an open switch?

Back

An open switch breaks the circuit, stopping the flow of electricity and turning off the connected devices.

Front

What is resistance in a circuit?

Back

Resistance is a measure of how much a material opposes the flow of electricity, slowing it down.

Front

What is voltage?

Back

Voltage is the electrical force that pushes electric charges through a circuit.

Front

What is current?

Back

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

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 same current flows through all of them.

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

What happens if one component fails in a series circuit?

Back

If one component fails in a series circuit, the entire circuit stops working.

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.
