Voltage Variation In Capacitor

Voltage Variation In Capacitor. The characteristics of voltage fluctuations depend on the load type and size and the power system capacity. One of the most notice­able effects of these stresses is the phenomena of capacitance variation.

If the bias voltage is different from the specified value, the capacitor will offer a capacitance that is different from the rated value. It helps in the smooth current fluctuations. For instance, if you choose a capacitor of 4.7 microfarad designed to operate at 16 v, it may offer a capacitance as low as 1.5 microfarad while working at 12 v.
