What is an electrical circuit?

Back

An electrical circuit is a closed loop that allows electricity to flow, consisting of a power source, conductors, and a load.

What is a conductor?

Back

A conductor is a material that allows electricity to flow through it easily, such as metals like copper and aluminum.

What is an insulator?

Back

An insulator is a material that does not allow electricity to flow through it easily, such as rubber, plastic, or glass.

What happens when an object loses electrons?

Back

When an object loses electrons, it becomes positively charged.

Front

What happens when an object gains electrons?

Back

When an object gains electrons, it becomes negatively charged.

Front

What is a closed circuit?

Back

A closed circuit is a complete electrical loop that allows current to flow.

Front

What is an open circuit?

Back

An open circuit is a broken electrical loop that prevents current from flowing.

Front

What is a schematic symbol?

Back

A schematic symbol is a graphical representation of an electrical component in a circuit diagram.

Front

What is the function of a switch in a circuit?

Back

A switch controls the flow of electricity in a circuit by opening (turning off) or closing (turning on) the circuit.

Front

What is a load in an electrical circuit?

Back

A load is any device that uses electricity to perform work, such as a light bulb or a motor.
