Universal Transfer Characteristics for FET: A Universal Transfer Characteristics for FET is simply a transfer characteristic plotted with IDSS = 1 and VP = 1. Then, instead of the scales being calibrated in milliamps and volts, they are…
Universal Relay Torque Equation Derivation: Universal Relay Torque Equation - Most of the protection relays consist of some arrangement of electromagnets. These electromagnets have either current windings or voltage windings and in some cases both…
Universal Motor - Construction, Working Principle and Applications: A universal motor is a specifically designed series wound motor, that operates at approximately the same speed and output on either dc or ac of approximately same…
Universal Counter Timer: All measurements of time period and frequency by various circuits can be assembled together to form one complete block, called a Universal Counter Timer. The universal counter uses logic gates which are…
Universal Active Filter using Op Amp: With the advance of integrated circuit technology, integrated circuits with improved capabilities are appearing in ever increasing numbers. Innovative design methods and fabrication procedures have not only helped to…
Unit Step Function | Unit Ramp Function | Unit Impulse Function | Unit Doublet Function: a) Unit step function: This function has already been discussed in the preceding It is defined as one that has…
Unit of Energy | Fundamentals of Energy: The capacity of an agent to do work is known as its energy. The most important forms of Unit of Energy are Mechanical energy, Electrical energy and Thermal…
Uninterruptible Power Supply (UPS) - Block Diagram and its Workings: Uninterruptible Power Supply (UPS) - Most of us take the mains ac supply for granted and use it almost casually without giving the slightest thought…
Unijunction Transistor in Static Relay: Unijunction Transistor in Static Relay is a three terminal device with only one pn-junction. It is made up of n-type silicon wafer having two base controls and a p-type alloy…
Uniform Field Electrode Gaps: Sphere gaps, although widely used for voltage measurements, have only limited range with Uniform Field Electrode Gaps. Hence, it is not possible to ensure that the sparking always takes place along…
