Energy and Circuits

Front

What is energy?

Back

Energy is the ability to do work or cause change. It exists in various forms, such as light, heat, and electricity.

Front

What is an electric circuit?

Back

An electric circuit is a closed loop that allows electric current to flow, powering devices like lights and bells.

Front

What are the two main types of electric circuits?

Back

The two main types of electric circuits are series circuits and parallel circuits.

Front

What happens in a series circuit?

Back

In a series circuit, all components are connected in a single path, so if one component fails, the entire circuit stops working.

Front

What happens in a parallel circuit?

Back

In a parallel circuit, components are connected across common points, allowing current to flow through multiple paths. If one component fails, others can still work.

Front

What is a fuse?

Back

A fuse is a safety device in an electric circuit that protects against overload by breaking the circuit if too much current flows.

Front

What is the role of a switch in a circuit?

Back

A switch controls the flow of electricity in a circuit by opening (stopping the flow) or closing (allowing the flow) the circuit.

Front

What is solar energy?

Back

Solar energy is energy from the sun that can be converted into electricity using solar panels.

Front

What is the function of a lightbulb in a circuit?

Back

A lightbulb converts electrical energy into light energy when current flows through it.

Front

What is the purpose of a battery in a circuit?

Back

A battery stores chemical energy and converts it into electrical energy to power devices in a circuit.
