Stray Resistance, Stray Inductance and Stray Capacitance
Stray impedance There is no perfect or ideal component in the world. Any wire or conductor forming an...
What is the function of Coupling Capacitors?
A coupling capacitor is used to connect AC input of one stage to successive stage, while DC voltage...
What are X Y Capacitors?
Radio Frequency Interference (RFI) and Electromagnetic Interference (EMI), emanating from electronic devices, switching circuits, chopping circuit devices using...
How is Metallized Film Capacitor Winding Done?
Capacitor winding made using metallized plastic film needs great care and precautions in manufacturing. Metallized film thickness can...
Why is reactive component of impedance termed Imaginary?
This question is often in the minds of learners – as to why the reactance or ‘imaginary resistance”...
What is Meant by Power Factor Correction in a System?
Most load in a grid / power system consists of motors, lighting, pumps, welding, electromagnetic appliances etc., which...
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...
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,...
