Differences between a Phasor and a Vector

If someone ask you whether current and voltage are vector or scalar quantity the obviously you will answer that they are scalar quantity. Next, the question arises if current and voltage are scalar quantity then why do we represent then in form of vector which is famously known as Phasor? We will discuss here this … Read more

What is Choke Coil?

If someone chokes a person, they can’t breathe, the flow of air is stopped. The name Choke comes from same idea. There is some energy that we want to Choke or prevent flowing in our circuit in or out of our circuit. We might want to prevent the power or ground lines in a circuit … Read more

Parallel Resonance Circuit – A Rejecter Circuit

What is Parallel Resonance Circuit? Parallel resonant circuit is a generic term which consists of resistor, inductor as well as a capacitor in parallel connection. A parallel circuit containing a resistance, R, an inductance, L and a capacitance, C will produce a parallel resonance circuit when the resultant current through the parallel combination is in … Read more

Q Factor / Quality Factor of a Coil

The ratio of the inductance L to the resistance R of a coil remains constant for different winding arrangements in the same volume and shape. It makes sense to define this value as a figure of merit to distinguish different coil structures. The quality factor Q is defined by this ratio of L and R. … Read more
