Passive voltage response to injected current step is not instantaneous, why not? Key words: time constant, resistance/capacitance properties

Commercially available strain gages, typically, have nominal resistance of either 120 or 350 Ohm. Discuss the advantages and disadvantages of each type in terms of measurement accuracy/precision and sensitivity.

(b) What additional component would you add to an ideal current source to "model" realistic non-ideal behaviour and why?

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

Cyclic Voltammetry and Charge-discharge The given figure is the Galvanostatic Charge-discharge curves of a supercapacitor made with MnO2 coated on a CNT electrode.  Potential is measured with respect to time by applying different current densities. Based on the plot, answer the following questions   4. Is it possible to estimate maximum power of the device with this charge-discharge curve? If possible, explain how you would do it. (calculation is not necessary)
