AC Load Line of BJT: AC Equivalent Circuits - Capacitors behave as short-circuits to ac signals, so in the ac equivalent circuit for a transistor circuit all capacitors must be replaced with short-circuits. Power supplies…
AC Input: The, ac input modules that are commonly available work with 24, 48, 110 and 220 V. It is important to use the one that fits the needs based upon the inputs devices (voltage)…
AC Fundamentals: Let us discuss in brief, the AC Fundamentals necessary to analyse the networks consisting of various alternating current and voltage sources, resistances and inductive, capacitive reactances. An alternating current or voltage is the…
AC Field Strength Meter: AC Field Strength Meter is usually measured by introducing a small fixed capacitance probe into the field area and measuring the induced charge on it. Since the electric field between the…
AC Excitation System - Block diagram and Working Principle: This AC Excitation system consists of an alternator and thyristor rectifier bridge directly connected to the main alternator shaft. The main exciter may either be self…
AC Equivalent Circuit of Semiconductor Diode: Junction Capacitances - The depletion region of a pn-junction is a layer depleted of charge carriers situated between two blocks of low resistance material. Because this is the description…
AC Distribution System: Now-a-days electrical energy is generated, transmitted and distributed in the form of alternating current. One important reason for the widespread use of alternating current in preference to direct current is the fact…
AC Distribution Interview Questions and Answers: 1. What is primary distribution system and what is normal operation voltage of primary distribution ? Ans. Primary distribution system is that part of the distribution system which operates…
AC Distribution Calculations: AC Distribution Calculations differ from those of d.c. distribution in the following respects : In case of d.c. system, the voltage drop is due to resistance alone. However, in a.c. system, the…
ABCD Parameters of Two Port Network or Transmission Parameters or Chain Parameters: ABCD Parameters of Two Port Network are known as transmission parameters. These are generally used in the analysis of power transmission in which…
