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.

How would the hook up 3 resistors in a circuit to get a maximum current?
In series,
R = R1 + R2 + R3 + ...
The current in a series connection will only have 1 path. The current is the same through each resistor
What is the difference betbeen capacitor and condensor?
A: Both nomenclature are indicator of capacitance it can be used both ways. However the predominate usage is capacitor since it resemble capacitance
Will gain increased bandwidth also increase to some extent after which stability decreses?
A: The question not very well formulated. But i will try to answer it. Any amplifier will have the maximum gain and the wider bandwidth when it is in a open loop situation. As feedback is added both the gain and the bandwidth will decrease but stability will increase
Can a nokia bl-5j 3.7 volt battery be used to power LED's safetly and how?
A: It sure can but what is voltage iof the LEDS 3.2 V then you need to drop 3.7 to 3.2 v at ~20ma .5v / 0,02=27 ohms in series the LEDS are 1.8 you need 3.7- 1.8/.02= 100 ohms in series. The warning is the life of this setup is going to be short lived after the battery drain off the battery needs recharging if so it is better to supply the LEDS from the charger directly will last until the LEDS QUIT FUNCTIONING
What is collector bypass capacitor?
A: It is not a bypass it is a negative feedback to effect the input voltage, Bias is when a DC voltage is applied to insure proper operation
What is the current flow through the 10 Ohms load resistor in amps?
A: It takes two known to give results in ohm laws. You have given us 1
A: I am not sure but i think TEXAS INSTRUMENT they ha a flat pack of diodes to begin with,
Does photo diode requires supply voltage?
A: it requires a source of power only if it has to perform any usage
What is the cost of fixing the image of a plasma LG 42''?
A: My experience of fixing anything these days is not worth the hassle or the money, Replacement is the key. I rather think that there is no one trained or able to fix a plasma .TV. sorry
Transformer coils are normally used to step down power from high power lines to a power you can actually use in your house. This works through the ratio of windings on a coil to the windings on the output side.
According to ohms law...
V=I * R
So from the given values
V = 4.3*16 = 68.8 Volts
What is the difference between a 1000 micro farad capacitor and a 1500 micro farad capacitor?
about 500 uF
Can you use FR306 diode instead of BY399 diode?
The FR306 and BY399 diodes have different specifications, particularly in terms of voltage and current ratings. The FR306 is a fast recovery diode with a maximum reverse voltage of 600V and a current rating of 3A, while the BY399 is a standard rectifier diode with a higher voltage rating of 1000V and a current rating of 1A. If the application requires higher voltage capabilities, the BY399 would be more suitable; otherwise, for lower voltage applications, the FR306 can be used, but ensure its ratings meet the specific circuit requirements. Always check the datasheets to confirm compatibility before substituting diodes.
What type of electrical equipment cannot convert AC into DC?
A transformer cannot convert AC into DC.
What is Zeilke instrumentation?
types of spinal instrumentation. Zeilke instrumentation is similar to Cotrel-Dubousset instrumentation, but is used to treat double curvature of the spine. It requires wearing a brace for many months after surgery.
True or false a high resistance between the collector and emitter when a transistor is switched off?
yes , it has high resistance between collector and emitter on the off state.
Why appliances seldom connected in series?
A: They are designed to operate from 120v AC which is readily available in every house. To make them work in series likes a refrigerator the wires will have to carry twice the load to assume the same power needed not very desirable or practical
What is a high end frequency scanner?
A: It is a terminology to imply that the scanner will be used at the hi end of frequency as opposed to low frequency
A: It can be AC but DC provide a stable environment to get reliable results
What is conversion of TTl voltage level to MOS level?
A: TTL Vcc is fixed at 5v +/- .5 volts while MOS can be run at higher Vcc like 12 volts therefore there is a compatibility problem and a converter must be installed between this family of gates to make them compatible with each other. So a converter will do just that translate a TTL level to a MOS level
Do 5 1 ohm resistors equal 1 5 ohm resistor?
it depends on how we are connecting them.if 5 1 ohm resistors are connected in series then the equivalent resistance is 5 ohms.if they are connected in parallel then the equi resistance is 1/5 ohms.
What is the great advantage of using the parallel circuits in home?
in parallel circuit voltage remains same ..... so all the appliances run at their rated voltages without having any problem as real power supplied depends on voltage .... p=(v^2)/R
What does this ic do 8812cpdng4n35?
this ic is a system control ic for a 32 inch color tv vertical horizontal on /off remote control etc and carries 56 pins connected to it xs24Type your answer here...
