Effect of Frequency
a.From equation for given H p and μ
P v α √f
b.From equation the depth of penetration for a given material
δ α 1/ √f
c.From equation hysteresis losses
Wh α f
d.For a greater thermal conductivity of the material the frequency requirement will be high whereas for a greater resistivity of the material requirement of frequency will be less.
e.The flux density in ferromagnetic material will be higher than that in nine magnetic material hence in ferromagnetic material less frequency is required to produce same amount of heat.
Q. Internal Frequency Compensation of operational amplifier? Some op amps, such as the 741, have internal RC networks which are intentionally designed to reduce gain at high fr
Nodes analysis Analysis using KCL to solve for voltages at every common node of the network and as determines the currents by and voltages across every elements of the network.
Consider a CS JFET amplifier with the following parameters : R 1 = 350 k; R 2 = 100 k, R SS = 1200 , R D = 900 , R L = 1000 , R S = 2000 , ro = 15 k,gm = 6 × 10 -3 S,
Flicker noise: I’d like to plot the graph of the flicker noise found in the data sheet for the amplifier (will be provided later) and also generate the equation for that graph sho
A 2200-V, 1000-hp, three-phase, 60-Hz, 16-pole, wye-connected, wound-rotor induction motor is connected to a 2200-V, three-phase, 60-Hz bus that is supplied by synchronous generato
Q. Counters are used to realize various dividers in the schematic representation of the digital clock shown in Figure. The blocks labeled "logic array" are logic gate combinations
Explain the signals HOLD, READY and SID HOLD indicates that a peripheral such as DMA controller is requesting the use of address bus, data bus and control bus. READY is used to
What is XMS? XMS: The memory system is splits in three major parts as: system area, XMS (extended memory system) and TPA (transient program area). The kind of microprocessor in
High Voltage Distribution System or HVDS Adoption of HVDS (High Voltage Distribution System) through converting existing LVDS to HVDS reduces the technical losses appreciably.
By means of nodal analysis, find the current delivered by the 10-V source and the voltage across the 10- resistance in the circuit shown in figure.
