The Basics of Electric Circuits

Have you ever felt a shock from static charge or a live wire? Are they the same thing? This science lesson explains electric current, and how it's measured.

In this science lesson discover how current measurements in series and parallel circuits can be used to illustrate Kirchhoff's First Law and Ohm's Law.

The word voltage is often used in describing electrical machines, but it's not always understood. This science lesson gives a technical, yet simple explanation.

Ohm's law is one of the fundamental laws of electric circuits. In this lesson, learn about Ohm's law, and how to calculate and measure resistance.

Understanding Kirchhoff's Second Law is a bit challenging because it links together several electronics concepts. In this lesson, go through them with examples.
