This video breaks down how resistors work and why they’re one of the most essential components in every electronic device. From smartphones to power supplies, resistors help control the flow of ...

Embedded above is a short segment produced by Make about one of our most fundamental circuit components: the resistor. Although brief at just five minutes, it covers resistor basics and the historical ...

I get somewhat annoyed when I hear engineers who have some real-world experience or exposure casually dismiss a component, especially a passive one, as “simple.” It may be simple in concept or ...

Electricity powers everything from your phone to your refrigerator—but have you ever wondered how it’s controlled inside a ...

Determining the resistor values and assuring performance of the circuit associated with a photocoupler (also called an optocoupler or optoisolator) is simple in principle, but there are some points to ...

In 1971, Professor Leon Chua described and named the memristor, arguing that it should be included along with the resistor, capacitor and inductor as the fourth fundamental circuit element. The ...
