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.

(4 coulombs / 2 seconds) = 2 coulombs per second = 2 Amperes.
What do you mean by 3 dB cutoff frequency?
3db frequency is the frequency at which the value in the graph is reduced by 3db level
It's also known as the half-power point.
Why doesn't any current flow through the galvanometer in a balanced Wheatstone bridge?
There is no current flow through the galvanometer in a balanced Wheatstone bridge because, in the balanced state, the voltage on both terminals of the galvanometer is the same. Since the voltage differential in zero, there can be no current.
In the chip itself? No.
The packaging and interconnects often contain gold however.
- Bond wires are usually aluminum, but sometimes gold is used instead.
- Lead frames and pins are commonly gold plated to reduce corrosion.
- etc.
There is a type of discrete bipolar junction transistor that is doped with gold, but as far as I have been able to find this is not used in ICs.
Where can you get electrons besides from an electron gun or cathode ray tube?
Electrons are in atoms found even in the human body.
Why input gain of an amplifier is doubled from output gain?
The gain of a transister stage is determined by its biasing circuit design. The emitter of a transistor is affected by the input signal on the base. If the base forward biases the transistor, the emitter feels the potential of the colector. If the base reverse biases the transistor, the emitter is isolated from the collector and feels the potential of the emmiter biasing circuit.
The output signal at the emmiter is representitive of the signal on the base, 180 degrees out of phase. The amplitude of the output signal will be larger, depending on the biasing circuit design.
Who invented the plotter printers?
In 1953, the first high-speed printer was developed by Remington-Rand for use on the Univac computer. In 1938, Chester Carlson invented a dry printing process called electrophotography commonly called a Xerox, the foundation technology for laser printers to come.
What do ampere coulomb curie Faraday fermi hertz newton and ohm have in common?
each is a unit of measurement.
SDI stands for serial digital interference. It is a video interface used within broadcast environments and supports both SD and HD signals. It runs on a single co-ax cable with BNC terminations. As well as video, the signal carries audio and other ancillary data such as closed captions, content identification and test signals.
SDI is not found outside broadcast facilities so it will not be seen on domestic televisions or players.
Polarization curve is measuring the corrosion rate of the metal with respect to current and voltage.
What does the word amplified means?
By the dictionary: transitive verb
1: to expand (as a statement) by the use of detail or illustration or by closer analysis
2 a: to make larger or greater (as in amount, importance, or intensity) : increase b: to increase the strength or amount of ; especially : to make louder c: to cause (a gene or DNA sequence) to undergo amplification
intransitive verb
: to expand one's remarks or ideas
Probably not, I would assume you knew about the condition and had an idea that what you would be doing could make it worse. If perhaps you had a minor condition and work pushed it to a point of being a disability then maybe you would have an argument. You could always lie of course, but you will be traveling a rough road if you go that route. Now if your employer new about your condition and you were not asked to sign a waver and they hired you anyway you may have a case. I would talk to a professional first. A good lawyer, of course, could make most any argument.
For maximum power transfer, source resistance should match load resistance and source reactance should match load reactance with the opposite sign (so if the load is capacitive, the source should be inductive).
Solidstate rectifier versus tube rectifier in guitar amplifiers?
A: There is no difference much in performance. But if a tube is replaced by a solid state rectifier the gain would be approximately 100 volts and assuming the DC caps are rated for this higher voltage it would be OK. Since there is higher voltages the dynamic of the amplifier will change accordingly.
Where can you find a service manual for a Kenwood KR-6030?
Hi my name is Christian, I'm from Chile and I have a the oroginal manual of the kenwood kr 6030 if anyone needs the manual I can send it thrugh the mail. Sorry I forgot to leave my mail. It is "usnavyblue36@gmail.com"p.s If anyone has the manual for the receiver Pionner vsx 4800 I would appreciate sending me to my mail. thanks
P=IE
What voltage (E) will be dropped across the resistor? Current (I) = .090 A
Assuming 90 VAC dropped across the resistor, then P=90 x .090 which = 8.1 Watts.
Why you need operational transconductance amplifier?
Usually output of an amplifier is a voltage ,...but in case of Operational Transconductance Amplifier ,Iout (current ) is the output. This feature, makes it useful for Electronic control of amplifier gain .
When testing the 6-Pin PCIe connector with a multimeter what should the voltage read?
The 6pin PCIe connector supplies 12v DC on pins 1, 2(optional), and 3 (yellow wires). The other pins are ground.
