The first part, Short Circuit Current Duties of Circuit Breakers and Fuses — Part 1, which ran last month in the July issue of EC&M, provided the necessary background and illustrated the ANSI ...

Learn how engineers design electrical circuits by calculating the voltage, current and resistance of electrical components.

Despite their designed current-handling capacity, such circuits still need current limiters and circuit breakers to protect them from fault conditions.

Learn how engineers design electrical circuits by calculating the voltage, current and resistance of electrical components.

Inspiration for this circuit and all those that use this topology derives from the current mirror topology and the notion that a varying current in Rsense, and therefore the voltage across Rsense, ...

CMOS current reference circuits play a critical role in modern integrated circuits by providing a stable and reproducible current source that remains unaffected by variations in supply voltage ...

Using FETs as voltage controlled resistors. Using FETs as voltage controlled amplifiers and active mixers. Using FETs as voltage controlled phase shifters for processing music. Using FETs as voltage ...

Designed specifically for high-voltage sensing, a new generation of optically isolated amplifiers make monitoring and system protection circuits more accurate and easier to design. These iso-amps ...

In Part 2, we’ll do the same for low-voltage circuit breakers and fuses. It’s important to note that this discussion is intended only to illustrate (by way of example) the ANSI methodologies to find ...
