What are Passive Filters?
Filter circuit, by definition, segregates undesired frequencies from input before passing on to output side.
-
Why do Electrolytic Capacitors fail and even Explode?
Power Factor of an AC circuit or a system is defined as the ratio of active power (or real power) to apparent power. It is that fraction of total apparent power, which is consumed in doing a work, conversion into heat or some other form of energy.

How Can Electrolytic Capacitors work for AC Motor Starting?
Electrolytic capacitors are essentially polar components, and are rated for DV voltages. They cannot sustain reversal of polarity,…
