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.

Does the canon rebel XS shoot video?
No, the Rebel XS, being one of the cheapest D-SLR's on the market today, cannot shoot video.
What is the voltage across a 100-ohm circuit element that draws a current of 1A?
thanks to ohm,,who invented the answer.according ohms law,V voltage=R(element)xI amps.then.....answer is....100 volts.
A: These particular chips have laser cut resistor to insure resistance consistencies as required by designers. In these cases usually the use is for DAC or ADC . However they can be nothing more then pull up or pull down resistors for easier of packaging and layout,
Common-mode rejection ratio of an ideal amplifier?
The common mode rejection ratio of an ideal amplifier is infinity.
How is eddy current related to the thickness of the stampings of core?
A: Eddy currents are current losses if an iron bolt is used to hold the core lamination together that alone will cause losses. Usually a brass bolt is used to eliminate losses
What is Short circuit maintenance current transformer in automatic voltage regulator?
the SCT is used to provide excitation during short circuit conditions. under Short Circuit the voltage may drop below threshold level causing field current to drop, to avoid over excitation by the AVR, the short circuit provides the excitation energy required to maintain a voltage that allows protective devices to operate and isolate the fault.
the SCT is open under normal operating condition
What happens when high input signal is given to pnp transistor?
A high signal input to a transistor amplifier gives a high signal output provided it stays linear.
For normal operation of an npn transistor the base must be ground true or false?
False. For normal operation, an NPN transistor will have the base be more positive than the emitter and less positive than the collector, with the collector more positive than the emitter. Whether the base is grounded or not depends on the chosen design configuration of the circuit.
On a power supply is red a positive terminal?
On a car red is usually positive. But positive can also be black in some applications such as home wiring.
Use Ohm's Law and explain how 2 circuits have the same current but different resistance?
As we know V=IR, by changing the voltages in the two different circuits, we can maintain the same current even we have different resistance.
Why are parallel circuits considered current dividers?
They divide the electrons between different branches of the circuit.
I don't know, but I think he was a technical engineer.
The gain of a class A, common emitter BJT amplifier, a fairly standard configuration, is defined as collector resistance divided by emitter resistance, or as hFe, whichever is less. Assuming that we are operating in a linear mode, and hFe is not a limiting factor, then the emitter resistance being greater than the collector resistance simply means that the gain is less than one.
From where can one purchase Weller WES51 Analog Soldering Station?
The weller WES51 analogue soldering station can be purchased from retailers like Amazon and Ebay. There are also independent retailers such as the testequipmentdepot who offer this tool too.
Cascade connections refers to the series connection of amplifier stages, networks, or tuning circuits in which the output of one feeds. The cascade connection is also known as the tandem connection.
What is characteristic equation in control systems?
Set 0=(denominator of the System Transfer Function), this is the Characteristic Equation of that system. This equation is used to determine the stability of a system and to determine how a controller should be designed to stabilize a system.
INDUCTORS are a type of passive electrical devices that are used to store energy from magnetic fields and release it when needed.
The electronic component(mostly a coil) which opposes the changes in current in circuit is called an inductor . The ablitity to oppose the change of current flowing through is it is called inductance of the coil / inductor .The inductance of an inductor may also be defined as ablity to produce induced voltage when current varies through it .
Duties of high voltage switch?
It is used by utility linemen for isolation purposes. If a power line needs repair it is done de-energized. By isolating the damaged section with the isolation switches the rest of the utility customers can remain on the grid (energized) and not have to be without power until the damaged section of line gets repaired.
What are the small glowing particles in laser beam?
usually dust of some kind, occasionally water vapor, reflecting the laser light. I am assuming, of course, the part of the beam outside the excitation tube.
What was the allies strategy for winning the battle at midway?
Knowing the plan, and hitting them with their decks full.
The feature that enables an electronic link between different sections of an electronic document?
he feature that enables an electronic link between different sections of an electronic document
No, a Diac cannot trigger an SCR because when the Diac turns ON, the current through the Diac is around 9 mA. The gate threshold current of an SCR is typically 5 mA, which is less. So the SCR can get damaged due to this high gate current.
