Give a short description of soft ferrites.
Soft ferrites and their applications: all non- metallic compounds are consisting of ferric oxide and one or two bivalent metal oxides as Nickel oxide, Zinc oxide or Manganese oxide. They have the resistivity of about, 109 ohm-cm that decreases eddy current losses at high frequency. These magnets made out of this have high coercive force and square hysteresis loop. Magnetic permeability of such materials is as high as from 10,000 to 30,000. These materials are fabricated in shape as- E, U, I, beads and self - shielding pot cores.
Flow of electrons - Electrons flow down a wire that is what current, is. Good conductors like copper and silver and aluminum have free electrons in their outer shells, and they jum
Define Shunt VAr Compensation? Shunt capacitors absorb leading VArs (i.e. they are used to supply lagging VArs) whereas reactors are used to absorbs lagging VArs. Capacitors an
State the features of Washing machines Microprocessor would be used to control the below features, for instance: - Water temperature - Time for every cycle - Wash cy
When delivering rated load a 10-kW, 230-V self excited shunt generator has an armature-circuit voltage drop that is 6% of the terminal voltage and a shunt-field current equal to 4%
Q. Illustrate Output-rate control? A system is said to have output-rate damping when the generation of the output quantity in some way ismade to depend upon the rate atwhich th
There is often a need to produce more than one voltage from a single supply using a voltage divider. For example, the memory components of many personal computers require voltages
Q. How do you calculate the insulation resistance of transformer and what is the minimum value? Ans. The insulation resistance of the transformer will be calculated by using
Currents induced in armature conductors of a d.c. generator are alternating. To make their flow unidirectional in the external circuit, we need a commutator. Moreover, these curren
The following data apply to a 100-kW, 250-V, six-pole, 1000-r/min long-shunt compound generator: no-load rotational losses 4000 W, armature resistance at 75°C = 0.015 , series-fie
