Electronics Engineering

Electronics Engineering is a branch of engineering that deals with practical applications of electronic components, devices, systems, or equipment. Electronics are devices that operate on low voltage sources, as in electron tubes, transistors, integrated circuits, and printed circuit boards and use electricity as part of its driving force.

What is the effect of the reverse bias on the width of the PN junction?

The holes and electrons move away from the junction and attracted towards the terminals as the positive polarity is connected to the n-side and negative polarity to p-side.

What is slope over distortion?

i believe you mean that the question is to do with the gradient of a line

the gradient of a line is the change in height divided by the change in distance

which is the same as slope divided by distortion

if a man goes up a hill and his height cahnges by 1 metres vertically and he walks horizontally 10 metres then the slope is 1 metre and the distortion is 10 metres.

Gradiend is 1 -10th or 10%.....

Explain Working principle of electrodynamometer type of instrument?

The working principle of a basic electrodynamometer instrument is same as the PMMC instrument. The only difference in this case is that the permanent magnet is replaced with two fixed coils connected in series. The moving coil is also connected in series with the fixed coils. The two fixed coils are connected to electromagnets in such a manner that they form poles of opposite polarity. As the moving coil carries current through it and is being placed in the field of fixed coils, it experience a force due to which the moving coil rotates. The direction of this force is independent of the supply voltage as the current flowing through fixed coils and moving coil is one and the same. If the direction of current changes in the moving coil, then the field direction also changes, thus making the torque unidirectional.

Why is midpoint biasing desirable?

Midpoint biasing is desirable because it enhances the accuracy and reliability of data analysis by reducing systematic errors in measurements. By centering values around a midpoint, it minimizes the influence of outliers and extreme values, leading to more representative results. This approach also helps in achieving a more balanced perspective when interpreting data, ultimately improving decision-making processes.

Is it true you got a power that you did not know?

If you are referring to an old Pokemon game where you can find a TM called ancient power or something like that, it is a move that depends on the abilities and type of the creature that you choose to teach it.

What are the five reasons why engineers study economics and management?

they innovate new things. by having a knowledge of economics and management they can forcast or can predict the utility,advantages,disadvantages of the product. also get to know the scope of the product and it's contribution in growth.

What Number Comes After Quadrillions?

The number one quadrillion has 15 zeroes in the short scale and 24 zeroes in the long scale.

Adding three zeroes in the short scale gives one quintillion. In the short scale, this is 1 followed by 18 zeroes (1,000,000,000,000,000,000), while in the long scale, this is 1 followed by 30 zeroes (1,000,000,000,000,000,000,000,000,000,000).

What is situational attribution?

when we attribute someone's behavior to being a product of their ENVIRONMENT

How do you know when a slow blow fuse is bad?

There's really no general way of knowing, it's all down to how sensitive the equipment the fuse is hooked up to is. There should be recommendations on what type of fuse to use.

What is the typical bandwidth of a satellite transponder?

38 MHz. digital bit-rates vary depending on compression, modulation, typically QPSK. Expect at least 30 Mbps.

How to identify the anode and cathode of DR 25 diode?

The cathode of a diode is usually indicated with a band.

In the absence of the band, consult the datasheet. Alternatively, use an ohmmeter that generates more than 0.7 volts at low current (a diode checker) and check conductance. The diode will conduct when the anode is more positive than the cathode.

What will happen if you use a 14 volt output in a 12 volt input?

Shouldn't be a problem. For example the unloaded voltage on a car battery is often around 14 Volts. Under load the voltage reduces.

What is a diode composed of?

diode is made by joining a P and N type semiconductor materials
