ctically the same reading irrespect-ive of which bars were used. The resistance of one or moresections of the arm.ature winding could also be found byusing Ohm^s law, R=E/C, or the resistance would be equalto the voltage divided by the current as shown on the am-meter. It must be remembered that… … FiG. 455 cuited, the voltmeter would show practically no readingbetween these bars; while between any other bars some de-flection would be obtained. An open circuit, or short cir-cuit will nearly always be found by examination, as thetrouble usually happens very close to the commutator con-nections…
