![The ratio arms of the Kelvin bridge (shown) are R1 = R
2 b a 350 12. The galvanometer has an internal
resistance of 350 12 and a current sensitivity of 160 mm
/ MA. The unknown resistance Rx = 0.1005 12 and the
standard resistance is set a 0.1000 12. A dc current of 4
A is passed through the standard resistance from a 2.2 V
battery in series with a rheostat. The resistance of the
yoke may be neglected (Ry = 0 which is a good
approximation for this problem). Answer the following
questions: E Hile 09 0 win R3 b. IA) the deflection of
the galvanometer mm The resistance unbalance
