A DC motor is any motor within a class of electrical machines whereby direct current electrical power is converted into … WebAC will display as zero voltage on a DC setting, regardless of the polarity. Reversing the leads and still reading zero will distinguish this from DC with reversed polarity if the meter displays zero for reversed polarity DC. Measuring DC on an AC setting will depend on the meter. The meter rectifies AC to turn it into DC for a reading. cell theory videoWebJan 26, 2013 · The motor torque is proportional to current. The voltage source is called back-EMF, and it's proportional to the speed of the motor. This is why a motor draws more current when it is loaded (or worst, stalled): with the speed decreased, the back-EMF is decreased, and it opposes the supply voltage less, resulting in higher current. cellthera brno
