Obviously, you don't want the voltage to sag. For computer power supplies, you want the power to be even, pure, and clean without any ripple.

Why do two ideal voltage source of unequal voltage cannot be connected in parallel?
If two ideal sources of unequal voltage are connected in parallel the higher voltage will provide a majority of the current (a two percent difference in voltage would provide an additional 5% of the current) and (in the case of batteries) the larger would provide charging current, quickly draining it.
An ideal machine would have an efficiency of?
A ideal machine would have an efficiency of 100 percent. For this to be possible, the amount of energy output by the machine would equal the amount of energy input. Because all machines have physical parts, some energy is lost to friction, heat dissipation, or other factors, so no machine can be an ideal machine.
What is the coefficient of discharge?
Coefficient of discharge of an ideal liquid can be defined as a ratio of actual discharge and theoretical discharge. where, Cofficient of discharge = Actual Discharge/ Theoretical discharge.
What is a safe room temperature for running a PC?
The ideal temperature of your room should be between 68-71o F You should not go below 50o or above 82o F.
Why ideal filters are not realizable?
Ideal filters are not realizable because it would require a impulse response that extends from minus infinity to plus infinity, and it would be also a noncausal system. It may be proved on the frequency domain using the Paley-Wiener Criterion, which states that a square integrable magnitude response function |H(f)| is physically realizable if \int_{-\infty}^{+\infty} \frac{| \log_e |H(f)| |}{1+f^2} df < \infty Any ideal filter would require H(f) to have magnitude equals zero in a bandwidth and that would make | \log_e |H(f)| | infinitely large and the condition above would not hold.
Where Can You Find a 72w Constant Voltage LED Driver AC 90-240V?
This switching power supply is ideal for DIY projects like light bulbs, motors and other electronics. The output voltage is DC 12V constant voltage, which means that no matter what the state of charge on your battery is, this power supply will output the same voltage. This Switching Power Supply is a smart choice for your home or office working environment
What is Impedance of ideal voltage source?
An ideal voltage source has no internal resistance, and a constant voltage output. In reality, all voltage sources (battery, generator, etc.) have some internal resistance, and their voltage may degrade or change over time.Ans 2: An ideal voltage source will have zero input impedance and the voltage can rise to infinity to supply the current.Read more: What_does_an_ideal_voltage_controled_voltage_sources_do
What is the difference between ideal and practical voltage source?
An ideal voltage source is a theoretical concept used in electrical engineering and circuit analysis. It is a voltage source that maintains a constant voltage output regardless of the current flowing through it or the load connected to it. In other words, an ideal voltage source has zero internal resistance and can supply infinite current at a constant voltage. In contrast, a practical voltage source is a real-world device that has internal resistance and cannot maintain a constant voltage output when a load is connected to it. The voltage output of a practical voltage source will decrease as the current flowing through it increases, due to the internal resistance of the source. As a result, the voltage across the load will be less than the voltage output of the source, and the difference is known as the voltage drop. In practical applications, it is important to take into account the limitations of practical voltage sources and design circuits that can operate within these limitations. An understanding of the behavior of both ideal and practical voltage sources is essential for designing efficient and effective electrical circuits. You also read more at electronicsinfos. com
What is Difference Between Current Source and Voltage Source?
A current source varies the output voltage to maintain the desired current. A voltage source has a constant output regardless of the current draw (up to the capacity of the supply, of course).
The characteristics of ideal power supply?
some are: 1.) zero output impedance. 2.) perfect voltage regulation, especially no voltage over/undershoot with stepped loads. 3.) over-current protection by hard limiting or fold-back. Others may have different opinions or preferences.
What is the input impedance of an ideal voltage op-amp?
To get all the voltage from a source to a target without loss you need voltage bridging, that is a relative low output impedance to a higher input impedance. Usualy the input impedance is more than ten times higher then the output impedance.An input impedance is called also a load impedance or an external impedance.An output impedance is called also a source impedance or an internal impedance.
The ratio of coils on the input side of a transformer to coils on the output side is the ratio of the input voltage to the output voltage?
I think you mean 'turns' rather than 'coils' (a coil is made up of a number of turns). The answer is that, yes, the turns ratio is the same as the voltage ratio, for an ideal transformer.
What is the voltage regulation of an ideal transformer?
Ideally the voltage regulation voltage of a transformer should be zero. It means when you change the load from no load to short circuit (theoretically, normally you don't want to burn the transformer windings) the output voltage doesn't change and remains equal to the no load voltage.
What are characteristics of an ideal diode?
An ideal diode:Passes current in one direction only. (Under forward bias).Has no leakage current (passes no current under reverse bias).Has no forward voltage drop. (No voltage loss under forward bias - a real diode has Vd~=0.7)See links for more details.
Why is rectified voltage storge in a capacitor?
Because a capacitor is ideal for storing energy over short periods, as in a reservoir capacitor in a power supply.
What is the angle between no load current and the applied voltage in an ideal transformer?
A: Transformer by itself goes not alter the phases the output can be in phase or out of phase depending how you look at it.
What is the voltage output if the transformer is connected backwards?
It doesn't really matter which way around you use a transformer, the primary winding is ALWAYS whichever winding you connect to the supply, and the secondary winding is ALWAYS whichever winding you connect to the load. For either connection, the turns ratio will ALWAYS equal the voltage ratio for an ideal transformer (or close enough for a real transformer).
