Learn how to use both active and passive buzzers to add sound to your Arduino projects.

¿Qué es el voltaje y para qué sirve? En este vídeo hablamos de su funcionamiento y de su importancia para entender cómo funciona la electricidad. Veremos el voltaje tanto para la corriente alterna como para la corriente directa,...

In this video we learn how three phase electricity works from the basics. We explain how three phase electricity is generated, how the voltages vary, how to calculate the voltages and vrms, what frequency, hertz and cycle mean and how...

Multi-LED circuit. How to design a circuit which uses multiple LED's or multi-colored LED's. We learn the basics in this video with full calculations to design electronic circuits.<br/>

How to make a simple solid state relay using an LED, a LDR and resistor. Shown with calculations.

In this video, we're going to learn how to use SMD LEDs in our electronics projects. SMD LEDs are a type of LED that are smaller in size than normal LEDs, which makes them perfect for some special projects

Learn how AC voltage varies with AC since wave and how to calculate the Vrms root mean squared, vmax, peak voltage, the frequency and voltage of different countries.

Learn to design and build printed circuit boards using this tutorial

This video shows how to measure DC voltage with a manual-ranging multimeter.

This is a review of all of the dimensions used in AP Physics C - Electricity and Magnetism.

An introduction to Resistance. We also define ohmic versus non-ohmic with graphs. We define the slope of the graph as resistance. There is also a discussion of a graph of Electric Potential Energy as a function of Position and we...

This video shows how to prove that the electric field outside a uniformly charged sphere is the same as if the charged sphere were a point particle. Using Gauss' law, the electric field is shown to be constant and dependent only on the...

Potato chips - you can never have just one. But why? Why do I eat an entire bag while sitting on the couch by myself? Well, in this video, we learn about what scientists (and advertisers) have discovered about the potato chip and what...

The video explains the basic principles of a simple electrical circuit and how to calculate current, potential difference, and resistance using equations. The video also applies these equations to a simple circuit diagram with a battery,...

Electricity makes our lives easier every day. We use electricity in our work and play. Because electricity is virtually unseen, it is often difficult to understand just where it comes from and how it works. By watching the video and...

A description of basic series circuit analysis with Arduino.

This video provides an overview of how to conduct a practical experiment to obtain IV characteristics for different electrical components, including resistors, bulbs, and diodes. The video explains the equipment and circuit needed for...

A walk through of the Basic Electronics section curriculum.

A description of basic circuit analysis with Arduino.

This is a lecture video on the turns ratio equation for transformers. The video explains how the potential difference across the primary and secondary coil of a transformer depends on the number of turns of wire in each of the coils. The...

This video explains the concept and composition of transformers, which are devices that can increase or decrease the voltage of an alternating current. It uses the example of transformers found on telephone poles to illustrate how they...

This is a tutorial video on transformers and how they change the size of an alternating potential difference. The video explains the structure and action of a transformer, which consists of two coils wound on a common iron core - the...

On June 19, the CERN Council in Geneva Switzerland approved the construction of a new 100-kilometer circular supercollider called the Future Circular Collider.
