Electricity powers everything from your phone to your refrigerator—but have you ever wondered how it’s controlled inside a circuit? It all starts with one small, powerful component: the resistor. In ...

What is resistance? The most common definition of resistance is the opposition to current flow—more specifically the flow of electric charge in a material. The circuit element used to model this ...

There’s a small, silent component hiding in almost every electronic device—from your phone and laptop to your TV and charger.

Suppose a plant has a high rate of electronics failures, daily loss of at least one motor bearing, and complaints of tingling or shock when people touch water fountains or production equipment. These ...

Scientists have discovered that certain barium titanate ceramics do not follow Ohm's Law. Applying a voltage to them gradually changes their electrical resistance. The work may help explain how ...

The Ohm’s Law pie chart is a fantastic representation that presents a lot of information in a concise and efficient manner. The Ohm’s Law pie chart is a fantastic representation that presents a lot of ...

Do you ever wonder how much of what we do you could figure out from scratch? Tying your shoe might seem simple now, but kids have trouble mastering the skill, and dreaming it up for the first time is ...

A new technique for embedding atomic-scale wires within crystals of silicon has revealed that Ohm’s law can hold true for wires just four atoms thick and one atom tall. The result comes as a surprise ...
