Improper voltage is the one of the greatest causes of failed compressors in three-phase units. We are allowed a 10% deviation over or under the unit nameplate-rated voltage. Most technicians know to ...

The primary purpose of a voltage reference (V REF) is to establish system accuracy. An analog-to-digital converter (ADC), for example, uses a reference voltage to set its full-scale input level. The ...

Welcome to the first in a series of articles focusing on electrical calculation basics. This month, we'll discuss the most fundamental of calculations — those for current (I) and kilowatts (kW). We'll ...

The analysis of magnitudes and durations of touch voltages in cable installations can provide electrical professionals with a better understanding of the requirements of Art. 250 of the NEC regarding ...

Capacitive charge-pump circuits are used in many applications. And though these circuits appear deceptively simple, engineers working on them need a thorough understanding of how they function. By ...

This is a simple means of calculating the required size of the input filter capacitor in a basic power supply, or calculating the peak-to-peak ripple voltage in an existing supply. It works by ...

A potential divider, also known as a voltage divider, is a simple yet essential circuit used to reduce voltage to a desired level. It consists of two resistors connected in series close seriesA way of ...
