Alternative Wiring: Suppose now that we had used instead a slightly different wiring setup, where the voltmeter was instead wired across both the ammeter and resistor (instead of just across the resistor). Draw the new circuit

The space between two 15-in.-long concentric cylinders is filled with glycerin (viscosity = 8.5 × 10-3 lb·s/ft2). the inner cylinder has a radius of 1 in. and the gap width between cylinders is 0.1 in. determine (a) the torque and (b) the power required to rotate the inner cylinder at 180 rev/min. the outer cylinder is fixed. assume the velocity distribution in the gap to be linear.
