Build a magnetically-activated door for your dog, cat, or other pet using an Arduino in this fun engineering project.

Dr. Forrester explains the production of electricity and materials used to insulate and conduct it.

An extension board or power strip comprises multiple sockets connected independently to a flexible power cable and encased in a shockproof plastic shell. It draws power from the wall sockets and distributes it amongst devices connected...

This video discusses the development of intelligent glass technology that can adjust its reflection properties based on external temperature, reducing heat and energy costs in office buildings. Additionally, researchers have created...

In this video, we learn about and derive equations for electric power using Ohm's law. We explore the relationship between electric power, electric potential difference, electric current, and resistance. We also discuss the unit of...

In this video, the basics of electric circuits are discussed. The components of an electric circuit such as wires, batteries, resistors, capacitors, and switches are introduced with their respective symbols. The concept of electromotive...

Good morning! In this episode of Flipping Physics , Bo reviews the concept of resistors in series using the anthropomorphic charge analogy. Learn how charges navigate through resistors and why they are considered in series. We also...

In this video, we explore the concept of terminal voltage in batteries. We explain how terminal voltage is different from electromotive force (emf) and how real batteries have internal resistance, causing the measured terminal voltage to...

Dr. Forrester discusses parallel circuits and complex circuits. She reads a complex circuit diagram by identifying how electricity is transported within the pathways.

Dr. Forrester reads a circuit diagram by recognizing such components as the wire, battery, open switch, closed switch, resistor, and wall outlet. She discusses what electricity can produce in circuits by naming such energies as light,...

Dr. Forrester defines static electricity by conducting a simple experiment using a balloon. She also identifies the two types of electricity by describing static electricity and current electricity.

Dr. Forrester defines the terms current, electricity, and static electricity by recognizing that electricity is a physical science that is important in daily life. She also compares and contrasts the properties of current electricity and...
