Problem 1 You work for a startup, Ohm’s World, which makes demo circuits for engineering labs. The circuit designer, Shanelle, on your team is currently on vacation, and you are the only member with circuit experience. Your boss sends you the following memo: URGENT!!!!!!!! Job Order #314 How does this thing work? What’s its status? I need to know NOW! You take a look at job order #314: We need a temperature control circuit that turns a fan on when the temperature gets above a certain threshold. You take a look at Shanelle’s work, and the following circuit and note is all you can find: V S3 is positive and is a fixed voltage source. V T of MOSFET is 2V. I still need to replace the voltage source models with actual components. Between, V S1 and V S2 , one will be a fixed source while the other will be a temperature sensor whose voltage difference increases with increasing temperature. With the given objective and Shanelle’s work, what conclusions can you draw about the circuit to make it work for your application? A. V S1 is the sensor and V S1 >0 while V S2 is the fixed source and V S2 >0 B. V S1 is the fixed source and V S1 >0 while V S2 is the sensor and V S2 >0 C. V S1 is the sensor and V S1 <0 while V S2 is the fixed source and V S2 >0 D. V S1 is the fixed source and V S1 <0 while V S2 is the sensor and V S2 >0 E. This circuit will never work for the job order objective
