(a) A rectangular block has the dimensions {Xw X h. When a battery with a voltage Vis connected across the end faces as shown in the left figure above, a current / flows through the circuit. If the same battery is connected across the top and bottom faces of the block as shown in the right figure, what is the current / that flows through the circuit? Give your answer in terms of/1. (Use the following as necessary: t, w, h, 11) 12 (b) Suppose = 4.40 cm, w = 2.2 cm, and h=1.60 cm; the battery voltage is 1.5 V and =3.30 A, determine the value of 12. Solution or Explanation (a) Let R, L, and A represent the resistance, length, and cross-sectional area of a wire. Further, let subscripts 1 and 2 represent the values for the left figure and right figure, respectively.
