Answer 2

Problems associated with AC potentio-meter:

Following are the problems associated with AC potentio-meter:

• The mutual inductance among various parts of the instruments disturbs the normal value of mutual inductance.

• The mutual inductance and inter capacitance disturb the potential gradient of the wires

• A very small change in reading of reflecting dynamo-meter instrument either in AC or DC calibration leads error in the AC current to be set at standard value
