A question for any electricians/EEs out there-- I have a small space heater, rated for 1500 watts, when I plug it in, it dims the lights more than I would expect. I think the lights are on a separate circuit, but I can't remember for sure. I measured the wall voltage, and it reads 120.0 V with the heater off and around 108 V with it running. The reading is the same on two outlets on the same circuit, one below where the heater is plugged in, and one on the other side of the room. Is a 10% drop in voltage normal for that kind of load in a new house? Does that mean roughly 135 watts (if my calculations are right) is being dissipated in the wall?
These voltage measurements were made with a standard cheap multimeter, if that makes any difference.
