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…

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…
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…
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…
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…
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…
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…
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…
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…
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…
what is the difference between ac and dc current
DC is a current that flows from a higher potential source to a lower potential load in a positive to negative direction. The alternating current is unidirectional. It changes the…
Why AC supply is used in homes?
Edison suggested that households be supplied with direct current. However, it is not advisable to use DC because it is extremely difficult to increase or decrease the power distribution requirement….
