A: I imagine op amps. If that is the case there are two sources of output errors related to the input. One is that the input diode while conducting are not at the same potential due to miss match of the diodes the other is current offset due basically for the same reason miss match of current pathways.

What is the purpose of a comparator?
The main purpose of a comparator is the conversion of ADC(analog to digital conversion). In its input two supply voltages are applied and their differnce determines either a high or low signal of digital signal like to make which bit is high and which is low in the form of V++ and V--. If the diffrence between the two voltages is greater means positive the output will be V++ and if lower means negative the output is V--.
What is the difference between a fully controlled and a semi controlled converter?
Fully controlled rectifier uses only SCR's Negative output voltages are obtained two quadrant control wide range control costly semi converter uses diodes and SCR's only positive output voltages are obtained one quadrant control only positive half cycles are controlled
What is the voltage gain of the FET amplifier?
It can be answered in two ways : 1. ratio of output & input voltages [Vout / Vin] i.e Drain voltage(Vds)/Source voltage(Vs). 2. multiplication of trans-conductance & drain resistance .
What are the two most popular operating voltages for residences?
120v and 240v
How do you change 240V to 220V?
In a residence the standard voltage runs between 110 and 120 Volts. Since there are two such sources of voltage you can combine the hots side of each and you'll get voltages between 220 and 240 volts (Doubling the standard). Appliances will typically run fine between 220 and 240 so you shouldn't have a problem.
What is your outlet output voltage in US?
In North America there are two standard voltages for the wiring of homes, 120/240 volts.
What conditions must be met before two alternators can be paralleled together?
before two alternators can be connected in parallel, the output voltage of the two machines should be the same, the phase rotation of the machines must be the same, and the output voltages of the two machines must be in phase.

What are the advantages and dis advantage of full-wave bridge rectifier compared with two diodes rectifier?
in full wave bridge rectifier, the input and out put voltages are same but in case of two diode rectifier the input and output voltages can be different as per requirement a there is a transformer in the circuit. The former is lighter and the later is heavier.

Hooking two sources to monitor with digital and analog connections one at a time?
The analog source needs to be upscaled to dvi and the upscaled output fed to a switcher along with the digital source, you can then switch between the 2 sources with one digital output to the monitor.
What is voltage offset?
Input offset voltage is the equivalent voltage at the input of an operational amplifier. If an amplifier has a voltage gain of ten and an input offset voltage of 10 microvolts, a level of 100 microvolts will appear at the output with no input. Manufacturers try to design an op amp so the input offset voltage is as small as possible to minimize this error voltage at the output of the amplifier, especially for applications where small voltages are being amplified.
What are two possible sources of error when measuring a sample's mass and volume?
Calibration error (the equipment gives the incorrect result) and false assumptions (the sample is uniform and solid).
What two voltages do you have in your home?
I'm not sure they're "voltages" but if you're talking about the circuits, then the two types are series and paralllel.
How does an Operational Amp work?
An operational amplifier is an extremely high gain differential voltage amplifier--a device that compares the voltages of two inputs and produces an output voltage that's many times the difference between their voltages. How the operational amplifier performs this subtraction and multiplication process depends on the type of operational amplifier, but in most cases two input voltages control how current is shared between two paths of a parallel circuit. Even a tiny difference between the input voltages produces a large current difference in the two paths--the path that's controlled by the higher voltage input carries a much larger current than the other path. The imbalance in currents between the two paths produces significant voltage differences in their components and these voltage differences are again compared in a second stage of differential voltage amplification. Eventually the differences in currents and voltage become quite large and a final amplifier stage is used to produce either a large positive output voltage or a large negative output voltage, depending on which input has the higher voltage. In a typical application, feedback is used to keep the two input voltages very close to one another, so that the output voltage actually falls in between its two extremes. At that operating point, the operational amplifier is exquisitely sensitive to even the tiniest changes in its input voltages and makes a wonderful amplifier for small electric signals.
