why armature resistance is very low as compare to field resistance in dc motor
resistance to current flowAn ohmmeter meassures resistance
Well u can use a digital meter and check resistance from end to end of each wire. The meter would read OL wich means an overload of resistance. Measuring voltage would be dangerous because u have to apply power. You do not use power when measuring resistance. But the process of measuring each wire may be time consuming. If you could find a schematic of the houses wiring it would help i isolating the exact wiring.
R = (density)(Length)/(Area) Unit of resistance is Ohms.
The arrow opposite the direction of travel is the air resistance or drag.
