Resistance in a Wire Lab 5

How about solving this using KCL equations? Thank you

In the textbox below, using your ideas of forces, partial charges or electrons, distortions, energy, and interactions, draw AND explain how permanently electretized fibers in the N95 mask attract particles of all sizes. What causes the particles to approach the electretized fibers? (Hint: this is the essence of what your

Nichrome ribbon resistor elements each has a resistance of 1 ohm. The element is made from sheet of nichrome alloy, 0.025 cm think. If the width of the ribbon is 0.3cm, what length is required per element in cm? Assume specific resistance of nichrome alloy to be 109microOhm-cm.

Write the application of extra high tension that have rating 66KV and what used for?

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.

5.) In a parallel circuit: A) Each branch of the circuit must have the same potential difference B) Each branch of the circuit can have a different current C) Both of the above D) None of the above 5) 6.) A semiconductor is a material that: A) Has a resistance between a true conductor and a true insulator 6) B) Behaves like a conductor under certain conditions and an insulator at other times C) Both of the above D) None of the above

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.

1- A). Which of the following could be used as a discharge device in an inductive AC circuit? a) resistor b) diode c) metal oxide varistor d) "a" and "c", not "b" B. What is the purpose of a discharge device used in conjunction with opening a highly inductive circuit? a) to minimize the possibility of damage to the circuits insulation as a result of a high induced voltage b) to minimize the possibility of endangering the life of the person opening the controlling switch c) to allow the magnetic field to gradually collapse, thus limiting the value of the self-induced ernf d) all of the above C. The high voltage induced by an inductor when its circuit is opened could be used constructively for a) an automotive ignition system b) an electric fence c) both "a" and "b" d) neither "a" nor "b"
