43. (a) Using Table 27-1 and Eq. 27-10 (or Eq. 27-11), we have ¯ ¯ ¯ ~ E ¯ ¯ ¯ = ρ ¯ ¯ ¯ ~ J ¯ ¯ ¯ = ( 1 . 69 × 10 8 · m ) µ 2 . 0A 2 . 0 × 10 6 m 2 =1 . 7 × 10 2 V / m . (b) Using L =4 . 0 m, the resistance is found from Eq. 27-16: R = ρL/A =0 . 034 Ω. The rate of thermal energy generation is found from Eq. 27-22:
