## Why do you need a common ground when driving a device using a MOSFET and an Arduino?

Why do you need a common ground when driving a device using a MOSFET and an Arduino? For example, if a battery that drives a device generates 9 volts, it produces a difference of 9 volts at its two terminals. That is, if you measure the voltage at the battery’s positive terminal with respect to another … Read more

## What is VDC power?

VDC is an abbreviation for “Volt DC”. DC stands for “direct current”, which means that the voltage is constant (in contrast to alternating current, alternating current, in which the voltage oscillates constantly between positive and negative polarity). What is VDC power? So “VDC power” means nothing in itself, but “12 VDC power” means power that is … Read more

## Why is earthing required?

Earthing provides a low impedance ground path for power if an insult fails and a live cable comes into contact with an exposed part of a device, causing the device to be live and potentially dangerous to use. Ground is also used to provide a neutral line reference voltage in most AC distribution systems and a … Read more

## Can waves be accelerated?

Yes,  wave can accelerate  . The electron matter  wave  in the atom is an example of a  wave  that keeps changing its direction. The steady state condition of quantum mechanics, however, requires that such a  wave forms eigenmodes of the Hamilton operator, which would have a fixed and quantized energy. Can waves be accelerated? Accelerating charges create changing electrical and magnetic fields. Changing electric fields … Read more

## How electricity generate?

Methods of electricity generation There are seven basic methods to convert other forms of energy directly into electrical energy: Static electricity through physical separation and charge transport (examples: triboelectric effect and lightning) Electromagnetic induction, in which an electrical generator, dynamo or alternator converts kinetic energy (kinetic energy) into electricity. This is the most common form of … Read more

## Why do we need of biasing?

Bias: is a term from no less than 400 years, which means “oblique or diagonal line”. It is not an error of assessment, it is a preference. If you research all synonyms of bias, you will not find any evidence of errors. What you will find are terms that are synonyms with moral wrong, like … Read more

## What is the purpose of a neutral wire?

What is the purpose of a neutral wire? The purpose of the neutral wire is to complete the 120 volt AC circuit by providing the path back to the panel where the neutral wire is connected and connected to the ground. The neutral wire is an insulated wire because it is part of the circuit in which … Read more

## Is a relay the same as a contactor?

Is a relay the same as a contactor? Contactors and relays have the same task of switching a circuit. If you look from the perspective of the application, you would have seen contactors in control panels of industrial engines or other heavy loads. While relays are used in low voltage applications such as switching an … Read more

## What happens if neutral wire touches a earth wire

What happens if neutral wire touches a earth wire With normal AC power supply, nothing happens in industrial applications, i. H. When 3-phase current is used. In these cases, Neutral is used to balance the 3 phases. It is advisable to make sure that all phases are loaded equally. When all phases are balanced, ideally … Read more

## Difference between isolator and circuit breakers

Difference between isolator and circuit breakers Main Difference is: Isolator is an off-load device while, circuit breaker is an on-load device. The isolator is a manually operated switch that disconnects the circuit from the mains and discharges the charges trapped in the circuit. Isolators have low resistance compared to circuit breakers. Both circuit breakers and circuit … Read more
