V=12 volts and R=100 Ohms. At a certain setting of the rheostat the ammeter reads I = 35 micro amps. Calculate resistance of the rheostat Rh at that setting and find Vh and Vr. What's the sum of Vh and Vr? Compare it to the voltage of the power supply. What conclusion did you draw from the comparison? Show work.
