I don't know if it is what you are referring to, but in another thread earlier today someone made the comment about current going up when voltage goes down (as per motors). This is a common misunderstanding with many people because they see current rise with undervoltage conditions on motors. However, the current increases because the motor is slowing, and its impedance is dropping. The rise in current is not because the voltage went down, per se.The relationship between current and voltge is dependent on the type of load. So your example may not defy Ohm's law.
i dont know what insulation you mean for a receptacle besides when i have 120 circuit why receptacle is 125 volts and not 120I don't know what you are asking. A 125 volt receptacle is rated that way mainly because of it's configuration but also it's insulation is designed for 125 volt use. Nothing to do with Ohm's law.
As far as your second question (I think) about the relationship between voltage, current and Ohm's law. For a given resistance, increasing the voltage across it will result in a corresponding increase in current through it. However, if you keep the voltage constant and increase the resistance the current will decrease. Is that what you are thinking?

120 volts is the "nominal" rating. We routinely see voltages above 120 and 125 is more the norm. We are usually starting at about a 126 volt reference level at the substation (5% above 120 volts).i dont know what insulation you mean for a receptacle besides when i have 120 circuit why receptacle is 125 volts and not 120
Where is that? Need more context.for the other part mike holt stated in one of his experments cut the feeder neutral and the flourescent bulbs burned he said because undervoltage current went high and caused the burned bulbs

Sorry. Don't have it. Not quite sure of the details of what Mike was saying so I can't be of much help.In a dvd about commercial calcualation
