![]() So, they are eliminated at the time of measurement. The reading of the AC potentiometer is affected by the external magnetic field.The non-inductive element is used for making the sliding wire and the resistance coil of the AC potentiometer which reduces the reading error.Thus, in AC potentiometer the potential is transferred from the same source as the current or voltage is measured. ![]() In AC potentiometer, the frequency and the waveform of the current must be same as that of the voltage being measured.The following are the important factor which must be considered for their operation. The operation of the AC potentiometer is quite complicated as compared to the DC potentiometer.
