Question

You are given a 44 kΩ resistor, a 1.5 kΩ resistor, and an unmarked, “mystery resistor”. You are told that the mystery resistor has an impedance somewhere between 5,000-6,000 kΩ. You can only accurately measure resistances less than 1,000 kΩ.

• i) How would you build a Wheatstone Bridge to determine the exact impedance of the mystery resistor? One resistor will need to be a variable resistor. Build the circuit and submit an image and URL to your circuit
• ii) What range of values must your resistor span for you to determine the exact resistance of your mystery resistor?
