In 1832 Faraday proposed that the apparatus shown in Figure P31.28 could be used to generate electric cur- rent from the water flowing in the Thames River.“ Two conducting plates of lengths a and widths b are placed facing each other on opposite sides of the river, a dis- tance w apart, and are immersed entirely. The flow ve- locity of the river is v and the vertical component of the Earth's magnetic field is B. (a) Show that the current in the load resistor R is abvB I= p + abR/w where p is the electrical resistivity of the water. (b) Cal- culate the short-circuit current (R = 0) if a = 100 m, b = 5.00 m, v = 3.00 m/s, B = 50.0 µT, and p = 100 N·m.
