Propose Snubber circuits that will take care of dv/dt, di/dt protection and provide Trapped energy recovery and save against the inductive kick from the load?

Two equal resistors Ra and Rb are connected in parallel and to a 120-volt source. What potential difference exists between the midpoint of Ra and a point that is one-third from either each of Rb?

Mask design. Silicon solar cell is made of Al thin-film electrodes on silicon using lift-off technology. The linewidth of Al electrode is 10 μµm and the spacing between the adjacent electrodes is 30 µm, diameter of the ring is 500 µm. There are two contact areas, 100 x 100 µm at the end of each electrode. Draw a mask, mark down the dimensions, and clearly indicate the tone (clear or opaque) of each region on the mask. Contact Aluminum thin film electrode Silicon

Draw the signal flow chart of the simple resistance network.a) Determine the variables.b) Establish relationships between variables (using circuit rules).c) Identify branches and nodes and draw the signal flowchart.

3. Fast help needed to answer this Engineeing question. Check image.   Postive feedback for right answer :)

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.
