See how this principle translates in to fluids and the Bernoulli equation as well as into electric circuits and the voltage law and finally into heat and thermodynamics through the first law of thermodynamics.

This activity will build upon the concepts taught in the lesson The Strongest Pump of All. The activity will pull together the concepts of bioelectricity, electrical circuits, and biology. It will allow the students the opportunity to...

Explore how a capacitor works! Change the size of the plates and add a dielectric to see how it affects capacitance. Change the voltage and see charges built up on the plates. Shows the electric field in the capacitor. Measure voltage...

A really fine and complete biography, quite lengthy. Some emphasis placed on his time at Princeton. A great deal of detail can be found here. Link here to the Joseph Henry House.

Working as if they are engineers who work for (the hypothetical) Build-a-Toy Workshop company, students apply their imaginations and the engineering design process to design and build prototype toys with moving parts. They set up...

An electron traveling through the wires and loads of the external circuit encounters resistance. In this tutorial, the concept of resistance is introduced. For an electron, the journey from terminal to terminal is not a direct route....

The integrated circuit fueled the rise of microelectronics in the latter half of the twentieth century and paved the way for the Information Age. An American engineer, Jack Kilby, invented the integrated circuit in 1958, shortly after he...

Review the key terms and skills related to Kirchhoff's loop rule, including how to determine the electric potential difference across a component.

Although he didn't start studying physics until he retired from the clock-making business at age 30, French native Jean Peltier made immense contributions to science that still reverberate today. Even with the primitive tools available...

Review the key terms and skills related to Kirchhoff's junction rule.

This Nobel E-Museum website commemorates the work of Philipp von Lenard and his Nobel prize achievement. This detailed resource includes a biography, Lenard's Nobel Lecture, and the "The Nobel Prize in Physics 1905 Presentation Speech."

Explore circuits and the flow of electricity. Create a saltwater tester using a battery and electrical buzzer.

In this step-by-step experiment, you will learn how to make a battery using four lemons and use it to light an LED bulb.

A teacher lesson plan which could be easily converted into an idea for a student project or presentation. This page describes activities in which the interconversion of chemical and electrical energy are investigated. Complete activity...

A collection of video lectures for a power system analysis e-learning course. Course covers topics like transmission line capacitance, transformer model, and power system stability.

A very simple device to convert light into sound can be made by wiring a solar cell directly to headphones (or an earpiece). The solar cell converts light into electricity and the headphones convert electricity into sound. The limitation...
