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 voltage output if the transformer is connected backwards?
It doesn't really matter which way around you use a transformer, the primary winding is ALWAYS whichever winding you connect to the supply, and the secondary winding is ALWAYS whichever winding you connect to the load. For either connection, the turns ratio will ALWAYS equal the voltage ratio for an ideal transformer (or close enough for a real transformer).
What is microstrip patch array antenna?
microstip patch array antenna is basically ,thecollection of antenna that give the double directive gain
Guy Kawasaki is best-known as one of the original Apple employees responsible for marketing and evangelizing the Macintosh computer (1984). Aside from being a familiar face in the tech world and a well-known blogger, today Kawasaki is a leading venture capitalist, best selling author and an Apple Fellow. He currently serves as the Managing Director of Garage Technology Ventures and CEO of Alltop.
If diode works properly in 0.7volts than why we you use ideal diode and practical diode?
In theory A diode clamps 0.7 volts across it but in practice the number is not exactly 0.7 volts because it can not be controlled. This is only the case with Silicon Diodes (clamping 0.7 volts), as Germanium ones, ideally clamp 0 Volts, but in practice it is not exactly Zero.
Basically, in practice it is not exactly 0.7 volts but when doing theory one assumes it to be 0.7volts for ease of operation.
What is the frequency range of a six foot dish antenna?
The size of the dish isn't as important as the length of the antenna. The antenna is INSIDE the little can at the focus of the dish. The length of the antenna is tuned to the wavelength of the frequency being received.
What is different of common emitter amplified with capacitor and without capacitor?
It depends on where the capacitor is located. If it is across the emitter resistor, then the gain of the CE amplifier will be higher at higher frequencies.
Remember that gain in the CE amplifier is collector resistance divided by emitter resistance, or hFe, whichever is lower. Placing a capacitor across the emitter resistor will serve to make the effective resistance smaller at higher frequencies, resulting in increased gain, up to the limit of hFe.
If this is not the intended location of the capacitor, then please restate the question and provide the capacitor location.
How can you make a button to lock the door that a small dog can use?
It depends on the lock and where the mechanism is. Need the year, make, and model in order to provide a better answer.
Locks that have a plunger type mechanism can have a modification made so the foot would activate the lock.
NO; frequency is the number of cycles per second or micro second. Pulse is the number of pulses per second in a pulsed Radar
What is meant by Single phase half controlled bridge rectifier?
This is actually called a single phase half converter and it is used to have an adjustable DC output voltage. It is like a bridge rectifier but two of the diodes are replaced with a solid state switch, SCR for example, and there is also a freewheeling diode in parallel with the load. A half converted can have an output voltage that is adjustable from 0.9*E to 0 volts. It does this be adjusting the firing angle of the switches. There is also a full converted and the difference is that it has an output voltage from + 0.9*E to - 0.9*E volts.
How do you find your microchipped dog?
A: A scanner is needed to identify the dog but to find the dog that is not implemented at this time. It could but a source of energy must be implanted at installation time
Infinite ohms is what a multimeter will read across an open switch or a broken connection. It means that no electrons will pass between the points being measured.
Calculate the broadcast wavelength of the radio station 93.70 FM?
1.0672358591248665955176093916756e-8seconds
__________________________________
The wavelength would be 3.1995 meters.
How do you find base emitter collector of npn transisitor using notch?
Find the notch in the transistor, turn it towards you, point the leads down. From left to right is the Emitter, Base , Collector.
What is the frequency of RC cars?
the most common are 27 megahertz which have colored crystals to tell your channel and spectrum which is a system of jumping frequency and are virtually interference free. everythings goin 2.4 and spectrum both basicly the same spectrum does not jump frequency it binds to the receiver of what ever you have and will only communacate with that one, for example you can have 1000 r/c cars or planes opperating at the same time and there will be no interferance.
What would work as a capacitor?
A capacitor is made by taking two sheets of conducting material and placing a non conductor between them. The sheets are then rolled up. A wire is attached to each sheet. One sheet is charged positive, the other is charged negative. A piece of equipment is placed between them. When a switch is thrown the positive and negative charges combine and all the electricity goes through whatever piece of equipment is there.

Which two Ethernet fiber-optic modes support distances of greater than 550 meters?
C. 1000base-lx
1000base-zx
That would be a CRT Monitor (CRT stands for Cathode Ray Tube), or the big clunky monitor that you had such a hard time getting rid of when you got your LCD
Yes.
How the resistance value for the linear resistance can be changed?
Resistance can be changed by strain over time and changes in the temperature. Resistance thermometers are sensors that are used to measure temperature by correlating the resistance of the RTD elements.
Digital computers calculate by manipulating encoded symbols using logic circuits.
Analog computers calculate in a wide variety of ways with continuous analogous representation of data.
