Answer
The rate at which energy is dissipated between points 1 and 2 is $~~10~W$
Work Step by Step
In part (a), we found that the potential difference between points 1 and 2 is $~~5.1~V$
We can find the rate at which energy is dissipated between points 1 and 2:
$P = i~V$
$P = (2.0~A)(5.1~V)$
$P = 10~W$
The rate at which energy is dissipated between points 1 and 2 is $~~10~W$.
