Explain ferroelectricity.
Ferroelectricity:- Materials of ferroelectric have a high dielectric constant that is non-linear that is, this depends to a considerable extent on the intensity of electric field. These materials exhibit hysterisis loops that are the polarization is not a linear function of applied electric field. When the center of gravity of the positive and negative charges into a body does not coincide in absence of an applied electric field, therefore substance has an electric dipole moment. Hence material is said to be spontaneously polarized and termed as ferroelectric material. That substance is termed as ferroelectric. This contains small regions termed as ferroelectric domains and all dipoles are parallely oriented in domain although different domains are randomly oriented into the absence of an external electric field. While the temperature exceeds a particular value termed as the Curie point, the substance loses its ferroelectric properties. Examples are: Rochelle salt, Barium titanate and Potassium dihydrogen phosphate.
Q. Briefly Explain Energy and Power? If a charge dq gives up energy dw when going from point a to point b, then the voltage across those points is defined as v = dw/dq If
Explain the TEST instruction. TEST: The TEST instruction executes the AND operation. The difference is as the AND instruction changes the destination operand, whereas the TEST
what is feedback?
Q. Show polarity markings for a single-phase transformer for (a) subtractive polarity, and (b) additive polarity.
why voltages are in multiple in 11
after course what can i do
In terms of negative feedback, there exists an analogy between the operational amplifier and the power-steering mechanism of an automobile. The hydraulic pump is analogous to the p
Q. Can you explain about Multiple Poles? Let us consider that F 1 (s) has all simple poles except, say, at s = p 1 which has a multiplicity m. Then one can write When
