## What Is the Difference Between Differential Gain and Common-Mode Gain? | A Detailed Comparison between Two Input Signals

The key difference between differential gain and common-mode gain is that differential gain refers to the gain applied to the difference between two input signals in a differential amplifier whereas Common-mode gain refers to the gain applied to signals that…

## Why Is Open Loop Gain Infinite in Op-Amp? | A Detailed Guide

The open-loop gain of an operational amplifier (op-amp) is considered infinite for ideal cases due to the input signal (differential or single) being slightly greater than zero.  In practical terms, it is typically considered very high. Open-Loop Configuration in Op-Amp…

## What Gauge Wire to Connect Two 12V Batteries in Parallel? |

4 and 6 wire gauges are typical wires used to connect two 12v batteries. The ideal wire to use for the majority of RVs and travel trailers is a 10-gauge wire. The maximum current between the batteries must be considered while choosing…

## Single Ended vs Push Pull | Which Amplifier is More Effective?

A single-ended “class-A” amplifier is less effective than a push-pull amplifier. The output power that can be generated improves the power that is available for a given supply voltage and is more than the continuous consumption rating of either transistor…

## How Many Amps Does a Ceiling Fan Draw? | Amperage of Different Ceiling Fans

Typically, ceiling fans draw around 0.25 to 1 amp. Although, the amperage varies depending upon the model, speed settings, and such. You can determine the amperage simply by calculating yourself or by contacting the manufacturer. In most cases, the amperage…

## How to Convert Transmittance to Absorbance? | Different Methods for Converting

To convert percent transmittance to absorbance, there are two approaches. The first is the computation approach, while the second is the nomogram method. Transmittance values range from 0 to 1 and the percentage transmittance range from 0% to 100% where…

## Can You Crimp Solid Wire? | Safest Way to Crimp

Yes, a solid wire can be crimped. Crimping is the process of joining two terminals of metal. Crimping a wire means joining a wire to a wire or a wire to a terminal without using soldering. In this process, a…

## UL 1558 versus UL 891 | Which Standard You Should Apply?

The basic difference between UL 1558 and UL 891 is- UL 1558 is a switchgear construction standard while UL 891 is a switchboard construction standard.  The construction of the switchboard UL 1558 has a fixed group mounting while the construction…

## How to Attach Wires to a Circuit Board Without Soldering? | Different Methods for Proper Attaching

Several methods are available to connect wires to a circuit board other than soldering. They include using hot glue, alligator clips, or electrical tape. The methods are simple and the tools are reading and available in most hardware and electrical…
