For the Wheatstone bridge of Problem 138, the bridge balances at the 98-cm mark when R 0
Question:
For the Wheatstone bridge of Problem 138, the bridge balances at the 98-cm mark when R0 = 200 Ω.
(a) What is the unknown resistance?
(b) What effect would an error of 2 mm in the location of the balance point have on the measured value of the unknown resistance?
(c) How should R0 be changed so that the balance point for this unknown resistor will be nearer the 50-cm mark?
