Give 2 examples of applications that use piezoelectricity?

Give a description of capacitive reactance and back up your description with examples/evidence.

Find the values of I and V for the circuits of Figure P9.37, assuming that the diodes are ideal.

You have developed an idea for using a poly Si surface‐ micromachined cantilever. Initially, you designed a process flow for creating this simple structure, and the process flow is detailed in the figure below. ( cross section view and top view)There are several critical errors with this process (things that won’t work or won’t produce the result). Please find the critical errors in this process flow and, where possible, suggest alternate approaches. Do not worry about the accumulation of errors, but rather treat each step assuming that the structure up to that step could be created.This structure is actually quite simple to make. Develop a simpler process flow and associated masks to create the final structure. Be sure to show cross‐sectional and planar views of all key steps in the process.

Identify the characteristics of AC and DC voltage. Runs at a higher temperature Answer 1Choose...DCAC More dangerous to transfer Answer 2Choose...DCAC Easy to produce Answer 3Choose...DCAC Easier to transform voltages Answer 4Choose...DCAC Voltage remains at a constant value Answer 5Choose...DCAC Cheaper to produce

Another name for the RMS value of current or voltage is ... O the effective value O the exact value O the true value O the reactance value

A solid specimen of dielectric dielectric constant of 4.0, shown in the figure has an internal void of thickness 1mm. The specimen is 1cm thick and is subjected to a voltage of 80 kV(rms). If the void is filled with air and if the breakdown strength of air can be taken as 30 kV(peak)/cm, find the voltage at which an internal discharge
