As the gauge shown is compressed/expanded the resistance of the strain gauge changes commensurately with thedirection and magnitude of load. Develop an understanding as to why the resistance changes i.e. increases ordecreases from its nominal value. Then, Assume a 5volt DC supply, and 350 Ohms as the balanced nominal resistance to our circuit where thedifferential voltage across A and B is zero. Assume that the Resistance-force sensitivity is 25Ohm/10Newtons. Find the voltage across A and B for +10N,-30N, +100N, -0.1N.

Many prototype circuits need simulation. One web-based simulation software can be located here - Using this software, answer the following Scenario: The logic to control the remote tripping coil of a circuit breaker is as below. Four (4) different sensors – A (Overload), B (Inverse time) C (Breaker open), and D (Low current). If either A OR B are on AND if both C AND D are off then this will activate the coil (breaker open). No output must be given for any other combinations or conditions.

i) The equation above contains really only three variables in it: Id, Vd, and T. All the other terms are constants. Since in most cases we assume temperature is fairly constant as well, we are really only dealing with two variables: diode current and diode voltage. Based on this realization, re-write the equation as proportionality rather than equality, showing how the two variables of diode current and voltage relate ii) Based on this simplified equation, what would an I vs V graph for a PN junction look like? How does this graph compare against the I vs V graph for a resistor? iii) When "P" and "N" type semiconductor pieces are brought into close contact, free electrons from the "N" piece will rush over to fill holes in the "P" piece, creating a zone on both sides of the contact region devoid of charge carriers.
