Flashcard on Simple Circuits

Front

What is a simple circuit?

Back

A simple circuit is a closed loop that allows electric current to flow, consisting of a power source (like a battery), a load (like a light bulb), and a conductor (like wires).

Front

What is the role of a battery in a circuit?

Back

A battery provides the electrical energy needed to power the circuit.

Front

What does a switch do in a circuit?

Back

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

Front

What is an LED?

Back

An LED (Light Emitting Diode) is a type of light source that emits light when an electric current passes through it.

Front

What happens when a circuit is closed?

Back

When a circuit is closed, electricity can flow through it, allowing devices like lights or fans to operate.

Front

What happens when a circuit is open?

Back

When a circuit is open, electricity cannot flow, and devices connected to the circuit will not work.

Front

What is electrical energy?

Back

Electrical energy is the energy made available by the flow of electric charge through a conductor.

Front

What is light energy?

Back

Light energy is a form of energy that is visible to the human eye and is produced by sources like the sun or light bulbs.

Front

What is motion energy?

Back

Motion energy is the energy of an object in motion, which can be produced by devices like fans or motors.

Front

What is a load in a circuit?

Back

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