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.

What is the schematic of sharp X2429ce integrated circuits?
hola buenas tardes quisiera saber donde puedo encontrar los diagramas de un circuito integrado marca sharp modelo x2429ce gracias
IC means integrated circuit the name controller refers to its function control.
A 10 uF and a 30uF are placed in parallel. What is the resulting capacitance?
Total parallel capacitance is the sum of the value of the parallel capacitors.
It uses the formula - Total Capacitance = C1 + C2 + C3.
Hopefully, you can do the math at this point.
How much charge is stored in a fully charged system when a 33uF capacitor is operating at 9V?
Q = CV
Q = Charge
C = Capacitance
V = Voltage
Q = 33uF*9V = 297uC
Equation for voltage across capacitor in series RC circuit is as follow,
vc = V(1-e-t/RC)
V = DC voltage source.
So theoretically time taken for capacitor to charge up to V volt is INFINITY.
But practically we assume 95% or 98% of source voltage as fully charge.
RC is the time constant which is the time take for capacitor to charge 63%. In this case time constant is
500uF*2.7Kohm = 1.3sec
Time taken to charge 95% = 3*T = 3*1.3 = 3.9sec
T = time constant
Time taken to charge 98% = 4*T = 4*1.3 = 5.2sec
Can you use transformer for DC supply?
No. Only Transformer could not be used for DC supply.If yoy need to have DC out put,then rectifier unit required .

How could two circuits have the same current but different resistances?
The equation, I=V/R (Current = Voltage/Resistance) determines the current, so if you increase both V and R, you will be able to get the same current (with a bit of adjustment to make it exact)
example:
10 Volts & 2 Ohms resistance = 5 Amps Current
20 Volts & 4 Ohms resistance = 5 Amps Current
Why does a series resonant circuit cannot be tank circuit?
A series resonant circuit has it's reactive components connected in series with each other; while the reactive components, as in a "tank" circuit, are connected in parallel with each other.
The resonant series circuit has the capability of producing usable increased voltage levels across each component at resonance, while the resonant tank circuit does not.
The resonant parallel, or "tank" circuit; has the dual capability of creating a situation whereby the input amperage level is reduced to minimum while, at the same time, a maximum amount of circulating amperage is created between the two reactive tank components at resonance.

Carbon is a resistor, meaning it conducts electricity, but not very well.
carbon microphone consists of two metal plates with a layer of small grains of carbon between. Each metal plate is attached to a wire which connects it to an audio receiver.
A current runs from one plate through the carbon to the other plate. The carbon molecules normally resist it somewhat, lowering the power flow. When a sound wave pushes down on the top plate, however, it squeezes the carbon molecules more tightly between the two plates. This increases their conductivity, creating more electric current. As the plate moves up and down with the sound wave, the current increases and decreases, creating an electric wave in the shape of the sound wave.
What is the ic number of and gate?
For two input AND gate it is 7408
for three input AND gate it is 7411
State three advantages of over-sampling?
1) It greatly simplifies the design of the low pass filter which follows the DAC, which has to attenuate the aliasing noise but not the signal. Oversampling increases the gap between these, simplifying the low pass filter.
2) It allows for interpolation and thus much lower sine wave distortion figures.
3) It allows for superior DAC architectures such as delta-sigma and 1 bit DACs.
consists of two r-s flip-flops wherein clock of the first is negated and applied to the second.it is used to avoid the problem of race-around condition by making sure that the first flip-flop is triggered during the positive going edge and the second during the negative edge of the clock pulse.

What is Ohms on a coaxial cable?
Resistance of wire is measured in Ohms (Ω) and depends on these factors.
The length of wire in feet.
The cross sectional diameter of the wire (circular mils).
The type of metal the wire is composed of (K). Most wire is composed of Copper or Aluminum
Here is the Specific Resistances (K) of these metals.
Copper - 10.8 Aluminum - 17.0
We can then use the formula...
R=K*L/Circular mils
"L" being the length of wire in feet
The above answer is correct if you are looking for voltage drop over a conductor length. When you bring coax cable into the equation, you are not looking for the wire ampacity for service distribution. If for some reason you are not familiar with coax cable, it is used for RF transmission. The only concern is the impedance match of the cable to whatever it is connected to, like a transmitter or antenna. A mismatch at the ends is detrimental because it causes a reflection of a portion of the energy. The greater the mismatch, the greater the reflected power. On my ham antennas I use RG8U. It is a coaxial cable with 52 ohm impedance For a good chart, see related links.
Answer: without a load is infinite. The coax when connected will definitely change impedance as frequency and lenght of cable are varied. At some frequency and lenght it can be zero impedance. All cables are designed for some impedance at a specific frequency and lenggt.
There are only three major blocks to a computer so the diagram is very simple. The ALU,I/O,PROCESSOR.
How the room noise detector will work?
If you make a noise, a man wearing just boxers will attack you
What is nominal zener voltage?
A zener diode has a voltage when it reachesbreak over it may be 5v 12vor other voltage as manufactured. The manufacture will produce a 5v zener or is it? This voltage can change from device to device but the mean or nominal voltage will be as close as 5v as possible. So when buying a 5v zener do not expect 5v absolute but a nominal 5 v
ZENERS are designed for a specific voltage [ THEREFORE NOMINAL] as mentioned above . depends on the voltage required it can be bought within a specific voltage -/+ a % of the breakdown
What is the function of Thyristor module in inverters?
Usually these devices will conduct during an AC phase cycles to charge a capacitor to produce DC.
What do the letters adc stand for?
There are hundreds of meanings of ADC, depending on the context. Some of the meanings are: * Analog-to-Digital Converter * Analog to Digital Conversion * Arizona Department of Corrections * Adult Day Care * Aide-De-Camp * Aerospace Defense Command * Assistant District Commissioner * Air Defense Commander * Area Damage Control * ...
How you find number of machine cycle?
Machines do not have a cycle unless it is repetitive in nature. in computer that would be called frame rate. airplanes uses this kind of computer to insure that all data is collected and accounted for withing a real time frame. Even a PC has these rates but they are called interrupt cycles requests. In other words stop service the interrupt and proceed.
