Energy And Circuit Study Guide

Front

What is energy?

Back

Energy is the ability to do work or cause change. It exists in various forms, such as kinetic, potential, thermal, and electrical.

What is a circuit?

Back

A circuit is a closed loop that allows electricity to flow from a power source to a device and back again.

What is the difference between a series circuit and a parallel circuit?

Back

In a series circuit, components are connected one after another, so the same current flows through all of them. In a parallel circuit, components are connected across the same voltage source, allowing multiple paths for current.

Front

What is a conductor?

Back

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

Front

What is an insulator?

Back

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

Front

What is static electricity?

Back

Static electricity is the buildup of electric charge on the surface of objects, often caused by friction.

Front

What happens when two objects with the same charge come close to each other?

Back

Objects with the same charge repel each other.

Front

What happens when two objects with opposite charges come close to each other?

Back

Objects with opposite charges attract each other.

Front

What is a battery?

Back

A battery is a device that stores chemical energy and converts it into electrical energy to power circuits.

Front

What is a switch?

Back

A switch is a device that can open or close a circuit, allowing or stopping the flow of electricity.
