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.

No diodes do not increase voltage the most common diode can be thought pf as a one way gate that will only allow the flow of electricity in one direction.
these diodes can be used in groups to form a rectifier which converts ac to dc
The measure of how similar different brands in the same category are perceived to be
A zener diode with a rating of 500 mW will pass 50 mA at 10 V. (Power = voltage times current)
Note: The question appears mis stated, in that it states a rating of 500 MW, not 500 mW. To my knowledge, there is no zener with a rating of 500 MW.
It is the active parts of an alternator. The rotor is the inside rotating part that is connected via slip ring to a DC voltage normally supplied by the exciter, that can be a DC generator on the same shaft as the rotor or it can be a diode bridge that is converting AC from the stator to DC and is regulated by the AVR(Automatic Voltage Regulator). The rotor serves is the rotating magnetic field that is induced in the stator where the output AC mains is generated
What is the meaning of coherent?
It relates to being clear and understandable. For example you would need coherence between two people working on a detailed or complex project, so they both know what they are doing and what the other is doing and the overall objective.
What are Types of electrical circuits that use ohm's law?
the types of circuits use in ohm's law are:
serise circuit
parallel circuit
serise parallel circuit
Answer
Circuits that obey Ohm's Law are called 'linear' or 'ohmic', and are mainly (but now always) confined to metal conductors, providing their temperature is constant. Those that do not (the majority) obey Ohm's Law are called 'non-linear' or 'non-ohmic', and include most metals (e.g. tungsten), electrolytes, gases, and electronic components such as diodes, vacuum tubes, etc.
When is short circuit 3 coming out?
as far as i know there will not be a short circuit 3 coming out any time soon

Can you use adapter with output 5v 3amp to operate adevice with 5v 1amp?
Absolutely. The first rule: Source voltage should be equal to the device voltage.
The second rule: Source current sould be higher than the cumulative of the device's current.
Air gap flux is termed as useful flux why?
Basically useful fluke is the flux that flows with in the magnetic circuit of an armature. That is why when there is an air gap the flux enters the armature which makes it useful flux! Hope that answers your question!
What is the output of AND gate if sine wave is input?
I assume the sine wave input is pure AC, meaning this signal is positive, and negative, as would come from a transformer winding. To not damage the fragile input to the AND gate, you should have a limit resister, say 1K ohm to 10 K ohm. Then the output of the AND gate will be a very clean square wave. It will be in phase with the input sine wave. You can add a small capacitor from the AND gate input to tr ground.
IMPROVEMENT: The best kind of gate to use for this circuit is called a "Schmitt Trigger", which will really clean up the signal. It is only available as inverting, 1, 4, or 6 per package. You can easily use an inverting NAND, and run it through 2 gates to get your phase back to what you want. So for what you are doing, use a 10K input, to a 100 pF cap to ground, going into one section of a 74HC14 (6 inverters in one package), and then go through another section, if you need to get back to 0 degree phase shift. With the 2 inverters in a row, you can have 2 phases available. Or, you can add another R-C delay between the 2 sections, and make the phase shift to whatever you need. 90 degrees, no problem. With 6 inverters, you can phase shift on and on, and make all kinds of poly phase outputs.
MORE FUN: With the Schmitt gate, you only need an R and a C from the output back to the input, and you will make a very stable Square wave generator. With a single diode, you can make a "one-shot" circuit, for constant pulse width. You can even make a PWM circuit, by DC biasing the input.
Why ammeter is connected in different way in forward and reverse bias zenner diode?
The ammeter is connected in different way in forward and reverse bias zenner diode. So that all of the board will work right going forward and reverse.
Which IC you can use in place of cd4047?
You can use the CD4017 decade counter as a substitute for the CD4047 in certain applications, particularly for generating clock pulses or timing applications, as both are used in astable and monostable configurations. However, it's important to note that the CD4017 is primarily a counter and may not directly replicate all features of the CD4047, such as its dual operation modes. Always check the specific requirements of your circuit to ensure compatibility. Other alternatives could include the NE555 timer IC, depending on the intended application.
Do metals conduct electricity?
Yes, metals are known for their ability to conduct electricity. This is due to the presence of free-moving electrons in the outer energy levels of metal atoms that can carry electric current through the material.
modulating signal is the message to be carried by the carrier signal.
What is the difference between instruction cycle and machine cycle?
an instruction cycle may consist of a number of machine cycles.
