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.

How do you remove a capacitor from a circuit board?
Correct method:
Two pieces of equipment are needed. A small wattage soldering iron and a de
soldering tool. Heat the junction point up until the solder melts. Use the de
soldering tool to remove the melted solder. Do the same thing to the other side
of the capacitor by heating and removing the solder. The capacitor should now
pull away from the PC board.
=====
Lazy method:
--One piece of equipment is needed. A small wire cutter.
-- Select one end/side of the capacitor. Position the jaws of the tool on
either side of the wire emerging from it. Then cut.
-- Position the jaws of the tool on either side of the intact wire emerging
from the opposite end/side of the capacitor. Then cut.
-- The capacitor should now pull free of the terminal strip or printed board.
principle refers to the basic objective of something. Operation refers to how it operates.

How does a speaker vibrate at different frequencies at the same time?
An infinite number of sounds can be mixed together into a single sound wave. The different frequencies don't matter, unless they are specific frequencies that cancel each other out. You'll notice that, even though you have only two ears, you can still hear all those sounds at the same time.
What is the Definition of beacon frequency?
Beacon frequency refers to the amount of space that beacons can reach. The beam coverage is measured to determine its frequency.
How do you send a digital radio signal to a FM radio?
Frequency Modulation must have a carrier whereby the frequency can be modulated by the signal
What info is stored in an IC color profile?
An ICC (International Color Consortium) color profile stores data about how colors should be interpreted and displayed across different devices, such as monitors, printers, and cameras. It includes information about the color space, such as the range of colors that can be represented, and the specific characteristics of the device, including color gamut and gamma settings. This ensures consistent color reproduction by describing how colors should be converted between different devices and media.
Controlling torque controls the deflection and tries to stop the pointer at its final position.
But due to inertia, the pointer oscillates around its final position before coming to rest. Hence damping torque is provoded to avoid this oscillation and bring the pointer quickly to its final position.
Thus the damping torque is never greater than the controlling torque. In fact it is the condition of critical damping which is sufficient to enable the pointer to rise quickly to its deflected position without overshooting.
0.205 W
Power is equal to voltage times current (P=V*I) in Watts, and from Ohm's Law, the voltage across a capacitor is equal to the current passing through it times the resistance (V=I*R). The power is then P=I2R. For a current of 5mA and a resistance of 8.2kOhms, (5*10-3A)2*(8.2*103Ohms) = 0.205 W.
Why twisted pair cable called twisted pair?
Twisted pair comes with each pair uniquely color coded when it is packaged in multiple pairs. Different uses such as analog, digital, and Ethernetrequire different pair multiples.
Although twisted pair is often associated with home use, a higher grade of twisted pair is often used for horizontal wiring in LAN installations because it is less expensive thancoaxial cable.
The wire you buy at a local hardware store for extensions from your phone or computer modem to a wall jack is not twisted pair. It is a side-by-side wire known as silver satin. The wall jack can have as many five kinds of hole arrangements or pinouts, depending on the kinds of wire the installation expects will be plugged in (for example, digital, analog, or LAN) . (That's why you may sometimes find when you carry your notebook computer to another location that the wall jack connections won't match your plug.)
How do you design a cascade connection counter?
If an 8 bit binnery counter chip is used a 8 input and gate is connected to the output of the counter and the output of the and gate is connected to the clock input of the next chip so that when the first counter get to 11111111 all outputs of the counter will be high and it will pulls the second counter once and the first counter will return to 00000000 and count again from 0 to 255 des. THIS IS NOT THE PROPER ANSWER I WAS SEARCHING FOR I NEED THE RIGHT ANSWER.
absolutely nothing happens...just reverse the probes of multimeter & measure it again...this time around it should come positive...
Reducing voltage in a circuit does not affect resistance?
Reducing voltage in a circuit does not directly affect resistance. It affects current. Resistance is an independent variable.
Ohm's law: voltage equals current times resistance.
However, reducing voltage and/or current does reduce power, which reduces temperature, which can change resistance because resistance is usually affected to some degree by temperature.
An AC electric supply has its voltage continously varying in a sinusoidal pattern at a fixed frequency of 50Hz ( i.e 50 sine waves per sec.) in countries following the British system & 60Hz for the American system.
The voltage variation over a single cycle increases from zero to a certain positive maximum voltage & then reduces to zero & follows the same pattern for the negative cycle where the voltage is negative with respect to a reference measurement point. This repeats continously.
This AC supply is advantageous for practical reasons of the voltage being easily stepped down ( or up ) with transformers as per the needs of consumers. Also certain AC motors have a very high mechanical conversion efficiency.
However there are certain applications where a DC supply ( akin to a continous fixed voltage from a battery ) is required e.g electroplating , DC traction motors which have a very high inherent starting torque. The DC voltage as per requirements is ideally fixed at a certain level ( it can be called a positive or negative voltage , which is essentially determined by the point of reference used for the measurement . The frequency of DC supply is essential zero. DC devices cannot be plugged directly into an AC supply & therefore a Rectifier unit which consists of one ( for very low power application ) or more Electronic Diodes in particular combinations which GATE the AC supply to prevent the voltage excursions of the opposite polarity from reaching the DC device. This rectification gives a DC supply which has some variations called ripple & is not an ideal DC. Depending on the application other components like capacitors or more sophisticated active electronic circuits are used to remove these ripples and improve the DC supply. Most DC devices have supply polarities to be observed i.e
the device may not work or get damaged if the DC supply polarity is reversed.
It may be noted that almost all electronic circuits work with DC supply , even though outwardly the user may be plugging the device in to an AC supply.
If there is a degradation in the DC improvement circuit it will be noticiable as a hum in audio amplifiers or a waving picture on the TV screen in older systems.
In modern devices use of special switching power supplies has made it possible to get almost ideal DC.
Why are dc signals that change called pulse trains?
DC signals that change are called pulse trains because they consist of a series of distinct electrical pulses that occur at regular intervals. Each pulse represents a sudden change in voltage or current, creating a train-like sequence when viewed over time. This term reflects the repetitive nature of the pulses, similar to a train of cars following one another. The characteristics of pulse trains, such as pulse width and frequency, are crucial in various applications, including digital communication and signal processing.
The forward voltage at which the current through the junction starts increasing rapidly, is called the knee voltage or cut-in voltage.
What do you understand by the multiple bar diagram?
This method can be used for data which is made up of two or more components. In this method the components are shown as separate adjoining bars. The height of each bar represents the actual value of the component. The components are shown by different shades or colors. Where changes in actual values of component figures only are required, multiple bar charts are used
Power Flux density is a function of distance from the transmitter so:
PFD(r) = 300kW*25/(4*PI*r^2) when r is in meters the value is in kw/m^2
