Delve into the fascinating world of resistors, a key component in nearly every electronic device we use today. Resistors are crucial for controlling the flow of electrical current in a circuit, ...

In other words, with the perfect setup, you could put a digital panel meter that reads the voltage in the circuit, and read the resistance directly. Zeroing it out would require more effort to get ...

Ellie and James explore series and parallel circuits. They also discuss the differences between current and resistance across different circuits and how to calculate them. JAMES: Hello and welcome ...

The “trimpot” is the standard solution to the analog designer’s occasional need to fine-tune a resistance in a precision circuit. But this old standby isn’t always available. For example ...

Negative differential resistance circuit built with BJTs and corresponding circuit symbol I just made up With this in mind, back in 2002, I came up with a two-transistor circuit where the negative ...

That’s because each branch has the same voltage across it, and only has the resistance of one bulb. Placing ammeters at different points in the circuit shows how the current is shared between ...

The parallel capacitor then re-charges the main capacitor slowly through the series resistance. The result is the main capacitors open-circuit voltage slowly creeps up to a value close to the original ...
