Why out put current increase in transformer with capacitance load?
ferranti effect...B.*If we use capacitive load the stator MMF aid the rotor MMF. It means that in times of capacitive load rotor flux and main field flux are additive. So the alternator voltage increase with capacitance loading.[By Akhtaruzzaman08]
What is ripple voltage in 12 volt power supply?
A: Ripple is a residual voltage evident as voltage following the AC input frequency. The ripple magnitude is a function of not enough of both filtering capacitance or overloading the output. Increasing capacitance will reduce the ripple or reducing the loading
Why during loading the voltage get decreased at output?
Output voltage (...of a transformer, for example...) will decrease as it is loaded because of the transformer's internal resistance. As output current increases/load resistance decreases, a larger voltage will be dropped across the internal transformer resistance. This same phenomenon is present in AC and DC systems (such as batteries).
Advantages of using electrolytic capacitors?
the have large capacitance value, power rating is high , and its constriction. To smooth power supply ripples.The output of a sinewave with the bottom waves cut off is a power supply without smoothing.You would get a hum in an amplifier if it wasn't smoothed by a large capacitance,say 400 Microfarads.On a 12volt supply as in a portable tv,the power supply smoother is around 2000 microfarads.The output waveform should be nearly a straight horizontal line with no ripples on it.
How does a high out of a cmos gate operate a cmos load?
In a CMOS (Complementary Metal-Oxide-Semiconductor) circuit, a high output from a CMOS gate indicates that the output transistor (typically the PMOS transistor) is turned on, allowing current to flow from the supply voltage (V_DD) to the output node. This high output state effectively charges the load capacitance connected to the output, bringing the voltage at the output node close to V_DD. Conversely, the NMOS transistor is off, preventing any current flow to ground, thus maintaining the high state. The combination of these actions allows the CMOS gate to efficiently drive the load while consuming minimal power.
Is external CD drive output or input?
Neither. Is Your hard drive input or output? Neither. It is simply a storage device as a flash drive or internal optical drive would be.
Is a optical drive input or output?
An optical drive is an input and output device. It reads data from optical discs like CDs and DVDs (input) and writes data to these discs (output).
If your LG TV only has an optical audio output and the DVD player only has an optical output can you hook it up like that and will it work?
No.... It must be output to input...
What is the importance gate capacitance in CMOS device?
For the gate to change state, the gate capacitance must be charged or discharged. Since the transistor driving the gate has a certain amount of output impedance (resistance), this together with the gate capacitance forms an RC network. The gate capacitance must charge through the driver's output impedance, and this takes time. So, gate capacitance limits the maximum speed at which the device can be operated. Decrease the capacitance, and you can clock the device faster!
Is it possible to measure capacitance using only one 555 timer?
yes, it is possible to measure capacitance using only one 555 timer for it's monostable operation. When the output is high time is given by the equation t=1.1RC. From the output pulse measuring t(high) and then by measuring R we can calculate the capacitance.
What is stray capacitance and how is different from ordinary capacitor?
Any two adjacent conductors can be considered a capacitor, although the capacitance will be small unless the conductors are close together for long. This (often unwanted) effect is termed "stray capacitance". Stray capacitance can allow signals to leak between otherwise isolated circuits (an effect called crosstalk), and it can be a limiting factor for proper functioning of circuits at high frequency. Stray capacitance is often encountered in amplifier circuits in the form of "feedthrough" capacitance that interconnects the input and output nodes (both defined relative to a common ground). It is often convenient for analytical purposes to replace this capacitance with a combination of one input-to-ground capacitance and one output-to-ground capacitance. (The original configuration - including the input-to-output capacitance - is often referred to as a pi-configuration.) Miller's theorem can be used to effect this replacement. Miller's theorem states that, if the gain ratio of two nodes is 1/K, then an impedance of Z connecting the two nodes can be replaced with a Z/(1-k) impedance between the first node and ground and a KZ/(K-1) impedance between the second node and ground. (Since impedance varies inversely with capacitance, the internode capacitance, C, will be seen to have been replaced by a capacitance of KC from input to ground and a capacitance of (K-1)C/K from output to ground.) When the input-to-output gain is very large, the equivalent input-to-ground impedance is very small while the output-to-ground impedance is essentially equal to the original (input-to-output) impedance.
Can digital audio output connect to digital optical audio input?
A coaxial digital output (usually an RCA jack) can connect to a digital optical input using a coaxial to optical digital converter. This is a small box that goes in between the two products.
Is a optical character reader a input or output device?

What are optical output devices?
if u multiply optical x input and input x optical then u will receive the input optical for ur result and this will be ur optical input. my answer is correct and it will work no matter what. if u have any problems go ask someone who cares. xx
Is a internal disk drive input or output?

Is an OMR optical mark reader an input or output device?
An OMR (Optical Mark Recognition) is a scanner that reads the reflection of light from a specially designed design.
