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.

A: NO the only way is to lift one lead and measure.
Carefuly ! Very Carefully.
Engineering technicians use the principles and theories of science, engineering, and mathematics to solve technical problems in a variety of engineering fields. Engineering technicians generally have 2 year associates degrees. A lot of techs just install or help engineers with the hands-on start-up or troubleshooting of systems & equipment.
Electrical engineering technologists assist engineers in the design, drafting, and technical skills to implement engineering ideas. EET's generally possess a 4-year bachelors degree. Although the term can be somewhat misleading, someone with a BS in Electrical Engineering Technology can obtain the same job as someone with a BSEE. The EET degree usually focuses on the implimentation of design, while EE focuses on design and theory. The EE degree generally contains higher level math courses than the EET degree.
Difference between spectrum analyzer and distortion analyzer?
The spectrum analyzer is used to do distortion analysis to the signal. Due to the fact that we don't have a pure generated signal. In reality, there must be some distortion. The distortion analysis is important in the communication field as well as in electronics.
Which oscillator circuit uses a tapped coil in the tuned circuit?
Several oscillator designs use a tapped coil in the tuned circuit. The most common is the Hartley oscillator.
A 4000-Ω resistor is connected across 220 V what current will flow?
A 4000-Ω resistor is connected across 220 V will have a current flow of 0.055 A.
Ohm's law: Voltage equals Current times Resistance
Voltage drop not exceeding what percent is allowed for feeders?
A voltage drop of no more than 3% is typically allowed for feeder circuits in residential and commercial installations. This helps ensure that the voltage level at the load remains within an acceptable range for proper equipment operation.
Define Maximum power point tracking of solar cell under partial shading conditions?
in shading conditions also the solar raditions will reach the earth i think this will not effect the solar panels and also the mppt in shading conditions also the solar raditions will reach the earth i think this will not effect the solar panels and also the mppt
The color pattern of the primary bands on a resistor are black, brown, red, orange, yellow, green, blue, violet, grey, white - representing 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.
Why are the wires twisted in twisted pair cabling?
In multi pair cable sets, for example a Cat. 5 cable, the wires of each pair are twisted to prevent mutual induction into the other cable pairs. The tighter the twist, the less amount of induction into the other cable pairs.
You may not know this, but Ohm first did the experiment incorrectly and came up with a wrong and very complicated equation for what is now called Ohm's Law. He even published a paper giving this wrong equation.
It was only after the journal in which his incorrect paper was published had been out for some time, that he began trying to replicate the experiment using different equipment. At this point he realized that the type of battery he had chosen for the initial experiments had an unusually high internal resistance, which had caused false readings and resulted in the wrong and very complicated equation.
Use of a different type of battery with a much lower internal resistance in later experiments produced our current correct and simple equation. He then wrote a new paper that retracted the original.
How do you match speaker ohms to match a 4 ohm ampandHow many speakers can you add?
The amplifier will have an output impedance of around 0.04 ohms. We don't use matching. In hi-fi we have always impedance bridging. Zout << Zin.
The damping factor DF = Zin / Zout tells you what Zout is.
Zout = Zin/DF.
If the damping factor DF = 200 and the loudspeaker impedance is Zin = 8 ohms, the output impedance of the amplifier is Zout = 8 / 200 = 0.04 ohms.
You see, there is no "8 ohm amplifier" with a 8 ohm output.
Scroll down to related links and look at "Amplifier, Loudspeaker, and Ohms".
it is the minimum current required to maintain the SCR in conducting state.
It is program status register.It i 8 bit ,bit addressable register.It consists of four maths flag.
Why is a demodulator needed to recover the pulse waveform?
The received waveforms are in the pulse-shape form. And yet the demodulator needs to recover the pulse waveform.
Reason: The arriving waveforms are not in the ideal pulse shapes.
Filtering caused ISI and signals appear to be "smeared" and not ready for sampling and detection.
Demodulator goal is to recover baseband pulse with best SNR and free of ISI.
What should you do after BE in electronics and telecommunication?
After completed my elecronics and communication ngineering i will prefer higher study, M.Tech IN DIGITAL COMMUNICATIONS.
Why is it important for all capacitors to display on their cases the maximum working voltage?
If the applied voltage exceeds they Max working voltage than capacitor can blow.
Name two devices which use current carrying conductor and magnetic field?
One device for increasing the magnetic field surrounding a current carrying wire, is to wrap the conductor into a set of co-axial coils.
A second device is to include a ferromagnetic material in the core of such a coil.
Why were flip flops called flip flops?
With shoes in mind:
Flip Flops are known as Flip Flops simply because when you walk you flip and flop your feet + it sounds EXTRA cool... .
With Digital Electronics in mind:
Flips Flops are known to be Bistable, meaning it can be stable in either one of two states, as shown below:
"0 or 1"
But the state of a Flip Flop doesn't remain constant the whole time, it continually "flips" from one state to the other, which serves as the very reason why they are called Flip Flops.
Can you plug in 2 instrument to an amplifier with 2 channels?
Unless the amplifier has two inputs, you cannot plug more than one instrument in. The two channels are used off of the input to change sound between clean and different distortion types, not for another instrument
