What is Transition and Diffusion Capacitance?

What is ferroelectricity? What is piezoelectricity? Make a hysteresis cycle pointing out and explaining the parameters coercivity, ferroelectric saturation, spontaneous polarization.

Example 1, given the two below displacements, fined the magnitude of the displacement 2D – E D = (6.00î + 3.00j – 1.00k) m and Ë = (4.00i – 5.00j + 8.00k) m %3D %3D

"Problem 1. In your textbook, Equation 11-5 defines Vrms = 0.707 VPEAK . Derive this relationship." See image of Equation 11-5. I don't remember how to do this. Please help! Please make legible, typed in equation form would be great. Thanks!

(4)In salient-pole machines, the flux-density wave produced by the direct-axis mmf is ( ) A)saddle-shape wave. B)quasi-truncated sinusoidal wave. C) sinusoidal wave. D) rectangular wave.

ds 3. Current head-on to point P: Consider the case where the current is heading straight toward the point where we want the magnetic field. What is the magnetic field at the point P shown? D P Hint: consider a small piece ds and think about what the Biot-Savart law tells you. HoI ds x î dB = 4rr2 Thin about the angle between ds and î.

Explain the basics of a sinusoidal voltage source?

In reference to the load, how are capacitors connected to help prevent voltage spikes and surges? Are capacitors connected in parallel or in series with the load?

What is the integral of a square wave? What is the derivative (differential) of a triangle wave?
