The study of electricity goes all the way back to antiquity. But, by the time electricity started to become more well known, a few familiar names started to appear. Edison, Galvani, and a few others really changed the way the world worked.

In this video Paul Andersen explains how Kirchoff's Loop Rule can be used to calculate the voltage of different components of a circuit. The sum voltage throughout an entire loop will sum to zero following the law of conservation of...

Mr. Andersen describes the relationship between voltage, current and resistance in an electric circuit. Ohm's Law is introduced through a circuit simulation.

John La Grou unveils an ingenious new technology that will smarten up the electrical outlets in our homes, using microprocessors and RFID tags. The invention, Safeplug, promises to prevent deadly accidents like house fires -- and to...

Paul Andersen shows how homeostasis reflects of evolution through time. The endocrine system shows continuity through flatworms, earthworms and vertebrates. However the respiratory system shows change as organisms move onto land. The...

How do magnets work? Why do they attract and repel at long distances? Is it magic? No... it's quantum mechanics, and a bit more, as we explain in this, the longest MinutePhysics video ever.

In this video Paul Andersen explains how electric circuits contain different elements which can be connected in series or in parallel. The following four elements are explained in detail; emf, resistor, capacitor, and switch. The...
