Motor Starting & Control Resistors
Motor Starting Resistors are used to reduce the voltage at the motor terminals and also decrease the starting current. Motor Starting Resistors are necessary because the self resistance of a motor armature is very low. When the voltage is first applied, excessive current will flow. For limiting this current, since there will be no resisting back electromotive force (emf),some series resistance can be added to the armature windings.

EMF Detector
ElectroSensor™
This EMF detector is an unparalleled value that offers fast, reliable, and user-friendly measurements of electromagnetic pollution. Since man-made alternating current (AC) is different from naturally occurring EMF, some sources say that even extended exposure of as low as 2 milliGauss may be harmful. Fortunately, once EMF sources are identified with your ElectroSensor you can moderate your distance and exposure.
