Solid Dielectric Materials and Composites Materials: A good solid dielectric should have some of the properties mentioned earlier for gases and liquids and it should also possess good mechanical and…
Current Divider Equation: In a parallel circuit, the Current Division in all branches. Thus, a parallel circuit acts as a current divider. The total current entering into the parallel branches…
SI Unit of Electrical Resistance: SI Unit of Electrical Resistance - When a current flows in a material, the free electrons move through the material and collide with other atoms.…
Bolometer: Bolometric measurements are based on the dissipation of RF power in a small temperature sensitive resistive element, called a Bolometer. This bolometer may be a short ultra thin wire…
Types of Encoders in Digital Electronics: By the use of a digital code, it is possible to identify the position of a movable test piece in terms of a binary…
Variable Resistor Network: Variable Resistor Network - The basic problem in converting a digital signal into an equivalent analog signal is to change the n digital voltage levels into one…
What is a Filter Circuit?: A network designed to attenuate certain frequencies but pass others without attenuation is called a filter. A filter circuit thus possesses at least one pass…
