Diodes do not have color codes as far as I know. The "turn on" voltage is usually in the ballpark of .4 - .8 volts, and is dependent on the type of diode (germanium, etc.).

You may be referring to resistors. Look up in google resistor color code, and this should help you. There will be three colored lines, two are the resistance, the third is a scaling factor.

For example, if the first two colors match 82, and the third matches 3, the resistor is a 82 x 1000 = 8.2k ohm resistor.

There may also be a fourth color; this denotes the resistance tolerance (1, 2, 5, or 10 percent). If the tolerance is 10%, the above example may range from 8.2k + / 1 820 ohms.

Because it does not allow ac to pass through it...

Silicon "zener diodes" with a zener voltage rating of 5.6V or higher operate mainly by avalanche breakdown, so both the 6.2V and 24V "zener diodes" are avalanche breakdown type (not zener breakdown type).

Gordon Moore observed in the early 1960s that the number of transistors that could be successfully integrated on a single integrated circuit chip was growing at an exponential rate over time. He then quantified this observation into an equation. This equation has come to be called "Moore's Law" and the growth in the number of transistors in a single integrated circuit chip has continued to follow that equation since then (even though many potential problems that could have stalled the growth have come and gone).

Yes

current = charge / time

= I = Q/t

Diameter of the piston head.

In perfect condition, the voltage variations does not occur..

Due to failure causes, voltage variations will arise

If the line impedance is Z0 and the load is ZL then connect the load using a transformer with N turns ration. N=sqrt(Z0/ZL)

50 Hz is the frequency of alternating current (ac) used by national electricity power services in Europe and several other world areas whilst 60 Hz is used in USA, Canada and many other countries in the world.

50 Hz means or specifies "50 cycles per second".

Hz is the international technical abbreviation for the scientific unit of frequency, the hertz.

VSI - Voltage Source Inverter. This is a referred to a type of converter topology that converts electrical power either from DC/AC to DC/AC depending on applications and with a intermediatory power stage with high frequency signals. Usually, this comprises a H-bridge driving some sort of resonant network and a rectifier converting the high frequency AC from the resonant network back to DC.

Amplitude modulation (AM) is a technique used in electronic communication, most commonly for transmitting information via a radio carrier wave. AM works by varying the strength of the transmitted signal in relation to the information being sent. For example, changes in the signal strength can be used to reflect the sounds to be reproduced by a speaker, or to specify the light intensity of television pixels. (Contrast this with frequency modulation, also commonly used for sound transmissions, in which the frequency is varied; and phase modulation, often used in remote controls, in which the phase is varied) In the mid-1870s, a form of amplitude modulation-initially called "undulatory currents"-was the first method to successfully produce quality audio over telephone lines. Beginning with Reginald Fessenden's audio demonstrations in 1906, it was also the original method used for audio radio transmissions, and remains in use today by many forms of communication-"AM" is often used to refer to the mediumwave broadcast band (see AM radio). Pulse-position modulation (PPM) is a form of signal modulation in which M message bits are encoded by transmitting a single pulse in one of 2M possible time-shifts. This is repeated every T seconds, such that the transmitted bit rate is M/T bits per second. It is primarily useful for optical communications systems, where there tends to be little or no multipath interference.

because normal capacitors does not have any polaririties.

Read out integrated circuit refers to integrated circuit specifically used for reading detectors of a particular type. These are used in detectors where the sensitivity is very low and using a discrete circuit may not be useful as noise may be large enough to cover up whole signal.

What happens to the current in a circuit as a capacitor charges depends on the circuit.

As a capacitor charges, the voltage drop across it increases. In a typical circuit with a constant voltage source and a resistor charging the capacitor, then the current in the circuit will decrease logarithmically over time as the capacitor charges, with the end result that the current is zero, and the voltage across the capacitor is the same as the voltage source.

uplinking

Because if the rated current is lower than the actual current, it causes resistance to the electrical flow which in turn is dispelled as heat.

A: Because it is a voltage amplifier the current will inversely reflect the voltage across a resistor

Yes they can, since anyone who puts in the effort can become a skillful computer hacker. However, electronic engineering skills won't help that much since most computer hacking is software related. Electronic engineering relates more to hardware.

Yes they are the same. A cathode ray tube (CRT) uses an electron gun to "shoot" electrons from the cathode to specific positions on the anode of the CRT.

ANSWER I assume you mean polling, where a master device requests the status of a slave device. Another option for a design would be to have the slave device alert the master device when its status has changed. In either case, the master device can then act on the slave's status change. For example, if a computer polls its keyboard, it reads the status at an interval that allows it to detect a keypress. For the other approach, the keyboard has a controller that samples the keyboard (usually much more frequently than the master computer would be polling) and transmits a key code to the main computer.

Current is directly proportional to applied voltage. Ohm's law.
