The movement of electrons to perform a useful function is called "static electricity." T/F - ANSWERFalse. The movement of electrons to perform a useful function is called ELECTRICITY The time it takes for an overcurrent protection device to open is directly proportional to the magnitude of the fault current. T/F - ANSWERFalse. The time it takes for an overcurrent protection device to open is INVERSELY proportional to the magnitude of the fault current. Fires can be caused by electric...
