How can a power supply measure a high capacitance capacitor accurately?
Therefore, by lowering the applied voltage, the power supply will be able to supply enough current to measure the high capacitance capacitor accurately. Table 1: Frequency and voltage settings for different capacitance range and class types.
What is the applied voltage of a capacitor?
