What would you like to do?
A: Depends on the circuitry involved an op amp normally has a 90 Db rejection from variation, Logic gates however are more sensitive to power supply variation for the simple point that triggering points changes which translate in false triggering and the circuits miss behaving

What will be effect on motor current when an induction motor is supplied with higher voltage than rated voltage?
motor magnetizing current will increase with increase in voltage, therefore power factor of motor will decrease and motor will draw more current than rated.
The usual voltages produced by the power supply in a standard personal computer system are 5 volts and 12 volts. For more information see the Related Link shown below.
It is the 'as if' voltage in an AC circuit. Referred to as Vrms 120 volts in your house is Vrms, the effective voltage, 'as if' it were DC 120V, can do the same work. But 120V…ACrms is a sine wave with a peak voltage much higher than 120 volts.
Put a seprate transformer. It will solve this issue
The power supply in a PC is a complex device using switch mode circuitry and transformers to generate +and- 12v, for modems and communications ports. +and-5volts for the… logic circuitry,3volts for the processor. All these supplies are generated and electronically regulated. It is such a waste when they are thrown a way still working. They are mini masterpieces of electronic engineering and are capable of starting a car!
There are always voltage variations to your house. The utility company is mandated to keep the fluctuations to within a 10 % tolerance. When heavy loads drop off the the utili…ty's grid the voltage momentarily rises and vise versa when a heavy load comes on to the grid the voltage momentarily drops. This is what the the utility company has to keep within their specified tolerance.
There are many possible reasons for this issue. Transformers that are dieing, Connections that are lose or wires breaking are three possible issues. This can become a very s…erious situation. Contact your electric supplier right away.
The two outside contacts (of four contacts) are connected to the power supply in the computer.
Depending on the power supply, +12, -12, +5, - 5 and ground. Some also use 3.3.
It convert 220v or 115 to -12v and +12v by using many components and step down transformer.
Changes in load.
In theory, voltage should be the same around the clock. In practice you may get a tad higher voltage at nights, as there's less load on the system. With most people asleep, th…ere aren't as many machines running.
