6. (a) The energy transferred is
U = Pt = E
2 t
r + R =
(2 . 0V) 2 (2 . 0 min)(60 s / min)
1 . 0Ω+5 . 0Ω
=80J .
(b) The amount of thermalenergy generated is
U = i 2 Rt =
2
Rt = 2 . 0V
1 . 0Ω+5 . 0Ω
2
(5 . 0 Ω)(2 . 0min)(60s / min) = 67 J .
(c) The difference between U and U , which is equalto 13 J, is the thermalenergy that is generated in
the battery due to its internalresistance.
