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.

Why deflection is necessary in cathode ray tube?
It is not necessary in a cathode ray tube, it is a side effect and is needed in the calculations to ensure that there are no errors.

What are the advantages of JCreator over similar products?
Some advantages of JCreator over similar products include custom colors, quick code writing, production wizards for easy access, and easy project viewing with the browser.
How do you design a RC coupled bjt amplifier using pnp transistor?
same as you would using an NPN, except the supply voltages are reversed
How do you drop voltage in parallel circuit?
it does not meet,positive goes to positive and negetive to negetive.
Missiles used in World War 2 used by the us?
The us during ww2 had really no advanced missles. The Germans had the best and only advanced strike missle, the widely known and feared v-1 and v-2. The Americans used missles as ungided support weapons or rocket artillery in in aircraft tanks and ships as support. In the end the us was limited to small unguided rockets then after Hitler's downfall stole and copied Germany's advanced missles and other designs.
GATE exam is a Graduate Aptitude Test for Engineers, its a exam conducted by IIT i.e all the seven institutions, by writing these exams u can do ur M.tech anywhere in INDIA. for more details visit gate exam.com.
How do you take out a micro sd chip in a laptop?
For most devices that use MicroSD cards, they're spring-loaded; press it in just a bit and it will probably pop out.
When a magnetic field and a wire are moved near each other the voltage produced is said to be?
Induced.
KCL (Kirchoff's Current Law) applies to any circuit, not just parallel circuits. The sum of the currents entering a node will always equal the sum of the currents leaving the node.
KVL states that the sum of the voltages around a closed loop is always zero.
The purpose of a diode is to direct the flow of current in a circuit. Diodes function by allowing current flow in only one direction (acting as a short when current is applied at one end) and resisting current flow from the opposite direction (acting as an open circuit). Electronic devices such as full wave rectifiers use a series of diodes to convert AC to DC current.
Acceptor atom create in semiconductor crystals?
If an acceptor atom is placed in a pure semiconductor, it will accept one or more electrons from the valence band of the semiconductor. This will permit positive holes in the conduction band to carry electrical current - the overall result is that the material will behave as a p-type semiconductor.
beacause ammeter is use to measure the current not to measure the voltage
Why ce configuration amplifier is commonly used?
generally CE amplifier is considered as the most common amplifier because of two reasons :-
1. it has a good current gain (almost >100) :- this is eslf -explainable as more the output more willingly it would be used as an amplifier
2. low input current :- this is the most important reason , if we recall the input current in CE configuration we will come to know that it is the base current . base current has less magnitude this helps the designer to control it easily when compared to higher order magnitude currents like collector and emitter current as
Can you continue to charge on charge on store accounts?
Store accounts can be pretty much charged on indefinitely. Provided one pays them off in a timely manner. If one does not, at some point a store will no longer honor a cardholders card because the cardholder has violated the service agreement by not keeping the account current (paying the bill).
Casual studies are study methods that test a hypothesis in a market situation to better understand cause and effect relationships.
What is the best frequency range for headphones?
As low as possible to as high as possible, but don't go just by frequency response. Anything by Sony or sennheiser are normally good. A good unknown brand I found were Urbanz. Decent frequency response is generally anything from 20Hz and lower to 25KHz and higher. For example, 10Hz to 28kHz is decent. Some professional headphones (such as professional sennheisers) boast 3Hz to 50kHz, but unless you are a music producer this is rarely necessary. Hope this has helped :)
What will happen if a diode is connected to capacitor?
the diode when forward biased will conduct
and during reverse biased condition(generally doring reverse biased condition ckt is open mens no current flows;when register is connected)current flows
but during reverse biased condition
1--for sometimes initially current flows due to discharging of capacitor.
2--then ckt will be having no current
What is the function of zero order hold?
Zero order hold is used in Digital - Analogue converters (DACs). It literally holds the digital signal for the sample time, then moves to the next digital sample and holds that signal for the sample time as well, in order to reconstruct the analogue signal.
Who manufacturers cathode-ray oscilloscopes?
Tektronics and Agilent (Agilent Technologies, a spin-off of Hewlett Packard) are top notch, but there are others.
Without knowing the capacitance of the capacitor, your question cannot be answered.
Our products need to get RoHS certificate?
EDX-2 RoHS Test Equipment (EDXRF) Analyzers are a popular solution to test electronics and various product lines for RoHS compliance. It can measure the 5 restricted elements in RoHS Directive: Cd/Pb/Hg/Cr/Br.
