Varistors or Voltage Dependent Resistors (VDRS): Varistors, also called the voltage dependent resistors (VDRs), show a high degree of nonlinearity between their resistance value and the applied voltage. They are…
What is Capacitor in Electronics?: What is Capacitor in Electronics? - Capacitor is a two-terminal element that has the capability of charge storage and, consequently, energy storage. The stored energy…
Solid Dielectrics Used in Practice: The majority of the insulating systems used in practice are solids. They can be broadly classified into three groups: organic materials, inorganic materials and synthetic…
DC Distribution System: It is a common knowledge that electric power is almost exclusively generated, transmitted and disÂtributed as a.c. However, for certain applications, d.c. supply is absolutely necessary. For…
