why is it that the voltage will drop if there is a high load?

Think of it this way.  Your car will slow down if I drop an elephant in your trunk while your driving.  \nA high load drags the voltage down.  \nThe power supply can't keep up with the amount of energy the load is wanting.

Just be sure that you are not overloading the UPS. Check the rating on it!

The resistance of the filament of the lamp varies with temperature. When the filament is at room temperature the resistance is much lower than when it is white hot. \n\nCurrent = V/R. If the voltage is constant and the resistance increases, the current decreases.

Think of the analogy between the flow of electricity and water where voltage is pressure and current is water flow.  It take voltage (pressure) to cause current (water flow).  Therefore, current (water flow) will occur in the direction under greatest voltage differential (pressure).  Because you may be working with more than one voltage source (two transformers or ttwo battery cells?) one of the sources may be adversely affected.  Are you working with AC or DC?  You may need to avoid connecting a circuit for example that would be like charging a car battery with the leads reversed.  Good luck.

When feedback voltage is lost to the AVR, there is still an open-loop control (voltage reference setpoint) as well as an inner stabilizer that will kick into action if the field voltage drops. Thru amplifier action, the field current will be boosted to compensate for the drop in field voltage. There are AVRs that have feedback from field current and field voltage to prevent exactly this sort of collapse. So you will not have terminal voltage regulation, but may be able to still supply power. If on the other hand, the field voltage collapses entirely, then as the previous poster writes, there will be no electrical power output. Read on IEEE AVR Types to get an understanding of this.

You probably have a problem with your wiring.  CALL AN ELECTRICIAN TO CHECK EVERYTHING OUT!  I know it sucks financially, what with it being the "chirstmas shopping season" and all, but what if you have a serious problem and it causes a fire...you could lose a LOT more than your things...people could get hurt.  Don't risk it!

A power surge can cause multiple drives/devices to fail at once.  Also, if your power supply starts to go out, it can take other components with it.

The damage may not be immediately evident, but little by little the components in a computer are damaged by Voltage Spikes. Voltage spikes occur, not just during electrical storms but also from other electrical equipment like fluorescent lights and electric motors.\nI thought that i was protected but I used to have component failures until bought a good surge suppressor and I don't mean the cheap things they sell in the computer stores. You need to get one that comes with a guarantee, like "This unit will perform as intended for 10 years or we will replace it free of charge".\nI have seen so call surge protectors that have lights on that tell you that it is working. After a voltage surge, a pop was hear and the thing rattled when shaken. The light, however, still came on.\nI recommend Innovative Technology  surge suppressors. They have an excellant sine wave follow device that I have been using for over 10 years. I have not had any hardware failures since I bought it.\nIf the computer is turned OFF, it can still be damaged. It needs to be unplugged to be safe.

Because it is against the LAW. The load could fall damaging property, hurting OR killing someone.

hi there\n\nevery adapter supplied with laptop has some range for controlling fluctuating volatage and its written on the adapter it self. but when the range is too much upside down it slowly start burning the battery element copper or aluminum wire and it is screwed up when it is burnt completely. in some countries like india people where this is a major problem they use ups (uninterripuble power supply).ithink u can buy good ups from APC and it will take care ofuar laptop

No, the voltages are different

Its fault with the socket or the wiring. Check them out. You have not mentioned the voltage. Wattage matter in performance. Its only the Voltage & Ampere that matters for working.

The PD will decrease as the current passing through it will drop due to current division

Ok...you guys got this all wrong.  Voltage doesn't travel.\nThis is simple:\n\nSeries:\nAll series stuff see the same current\n\nParallel:\nAll parallel stuff see the same voltage

There are two major causes of power outages: circuit overload and damage to power lines.\nCircuit overload occurs when an unusually heavy burden is placed upon the power grid. For example when we are experiencing extremes in temperature, winter or summer, heat and air conditioning controls are raised to maximum levels to provide relief from the extremes. This puts too heavy a load on the power grid and it fails.\nPower lines are damaged usually during storms from icing, trees downing the lines and lightning strikes.

A lot of static electricity in the air can cause "dry lightning".  I assume that is what happened.

b/c a constant amt. of electricity is going into it, and it will only get brighter if you add more electricity to it, or get a brighter bulb!
