Poles ÷ 2 = Take answer 1 and ÷ by answer 2 = - Correct Answer Know the formula for RPM 435 Pg. 5 If you are referring to a megohm meter, it is a test of the insulation properties of such things as electric wiring, motor windings and high power antenna mounts. We use a "megger" or "meg out" electrical wiring and equipment to see if it is shorted to ground or the frame in any way. The megger uses much higher voltages to check resistance than a normal Volt-ohm meter. Minimum resistance is 1 Meg Ohm - Correct Answer Know what a Megger is and what it does 636 Pg. 13 (1) A parallel connection. (2) A resistive element placed across the terminals of an armature to bypass a portion of the current. (3) A flexible electrical conductor designed to conduct current around the mechanical joint between two conductors. (4) The resistive element (Usually of very low resistance) used in parallel with a DC ammeter movement to bypass a calibrated portion of the total circuit current. - Correct Answer Shunt Overloads 425 All Pages Bad Ground - Correct Answer
