Front

What is a circuit?

Back

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

Front

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

Back

The 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 electric current to flow through it easily, such as copper or aluminum.

Front

What is resistance in a circuit?

Back

Resistance is a measure of how much a material opposes the flow of electric current, typically measured in ohms.

Front

What happens in a series circuit when one component fails?

Back

In a series circuit, if one component fails, the entire circuit is broken and all components stop working.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of circuit where there are multiple paths for current to flow, so if one path is broken, others can still function.

Front

What is the difference between series and parallel circuits?

Back

In a series circuit, components are connected end-to-end, while in a parallel circuit, components are connected across common points, allowing multiple paths for current.

Front

What is an ammeter used for?

Back

An ammeter is an instrument used to measure the current flowing through a circuit.

Front

What is a voltmeter used for?

Back

A voltmeter is an instrument used to measure the voltage across two points in a circuit.

Front

What materials are considered good conductors of electricity?

Back

Good conductors of electricity include metals like copper, aluminum, and silver.
