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.

Can switchboard explosion cause short circuit?
A short circuit is what usually causes a switchboard explosion.
What is the main distinction between digital and analog signals?
digital systems are nothing but may be based on microcontroller, or an electronics parts which are highly sensitive, fast response and light in weight. Where as analog instruments mainly consists of mechanical parts which indicates lower accuracy compared to digital.

What resistors do in oscillator circuit?
The same thing they do in every circuit, resist the flow of electricity.
That being said there are Many types of ossilators, and they can use resistors for many purposes.
The official definition of the word amplifier is "an electronic device for increasing the amplitude of electrical signals, used chiefly in sound reproduction."
How far will digital signal reach?
All of the unmanned space-exploration vehicles communicate with the tracking stations on earth in the form of digitally encoded signaling. That includes artificial earth satellites, the Hubble Space Telescope, the two rovers currently operating on Mars, missions to the planets, and a couple of machines launched many years ago that have left the solar system and are still in touch with earth. All space communication is digital. So I suppose the best answer to your question is: "Farther than you thought."
Why are SCRs connected in series?
they are not always connected in series, yes most are for circuit amplification purposes, but some SCR's are just used as an electronic switch by themselves. An example is copier circuits, they use alot of them in single use applications.
What is reciprocity theorem in antenna?
If a voltage is applied to the terminals of an antenna A and the current is measured at the terminals of another antenna B, then an equal current (in both amplitude and phase) will appear at the terminals of A if the same voltage is applied to B.

When one resistance or load in a series circuit gets defective the circuit becomes?
The circuit will become an open circuit.
What happens to a light bulb when put in series with a inductor?
When you put a light bulb in series with a inductor, the inductive reactance of the inductor reduces the current available to the light bulb, making it less bright.
For this effect to be noticed, however, you need a very large inductor. To cut the current in a 60W bulb at 120VAC/60Hz by one half, for instance, you need an inductor around 0.6 henrys.
How do you connect a motor to a picaxe 18M?
It depends. If you only want to turn the motor in one direction, then you could simply use a medium power mosfet (eg:IRF530) connected to an output pin on the PICAXE, and with a backward diode around the motor.
If you need to change direction, it's best to use an L293D, which allows independent bidirectional control of two motors.
What is locator in embedded system?
by contrast creates file that will be used by some program the copies the output to the target system later the output from the locatar will have to run on its own.

What is current gain and voltage gain?
Current gain is the ratio of output current divided by input current.
Voltage gain is the ratio of output voltage divided by input voltage.
Nothing more complicated than that.
The voltage must reduce by the same factor - that is Ohm's law.
How many things are needed to create a current?
A difference of potential (voltage) and a conductor connected to the voltage source will cause current flow. Not that you'd want to "short out" a voltage source with a piece of wire, but just the source of voltage and the conductor would permit current to flow. If you took a piece of wire and touched it to the terminals of a good battery, current would flow. It takes just those two things to create a current.
Is quantize one of the stages occurring in the process of analog digital conversion?
Yes. The stages are Sampling, Quantizing and Encoding (in that order)
The energy leaves as either a photon or phonon.
How do you say flip flops in spanish?
Most Spanish speaking people use the term "Chanclas" to refer to Flip-Flops, which simple means "sandals"
