What is the Significance of Q factor in AC circuits?
Quality factor Q is a measure of ‘goodness’ of a coil, inductor or capacitor, or a resonant circuit…
-
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,…
-
What is the Correct definition of Power Factor?
Current and voltage directly decide the power consumption in DC as product of these two entities. However, in…

How does current flow through capacitor?
There is always a curiosity as to how current passes through a capacitor, while there is an insulation material (dielectric) between its plates.
-
What happens if a capacitor of different value is replaced in a motor?
There is often a perception that replacing a defective capacitor in fans with one with higher value may help in getting better speed. What is the truth?

What Is the Difference Between Battery and Capacitor?
Battery and capacitors both store energy, and it is natural to have a doubt about their functions and differences. It is necessary to understand their basic differences.
