If turning the heater on increases the current through the wires by 10 times, does the power loss in the wires increase by 10 times, more than 10 times, or less than 10 times? Would a 10 times increase be consistent with P=IV? b) In this part of t ...

Stray voltage
Stray voltage is the occurrence of electrical potential between two objects that ideally should not have any voltage difference between them. Small voltages often exist between two grounded objects in separate locations, due to normal current flow in the power system. Large voltages can appear on the enclosures of electrical equipment due to a fault in the electrical power system, such as a failure of insulation.
