25. (a) From Eq. 24-35, we find the potential to be V =2 L / 2 + ( L2 / 4) + d 2 ln 4 0 d
(0.06 m / 2) + (0.06 m) 2 / 4 + (0.08 m) 2 = 2(8.99 109 N m 2 C2 )(3.68 1012 C/m) ln 0.08 m = 2.43102 V. (b) The potential at P is V = 0 due to superposition.
The biggest drawback of PAFCs is that they are expensive as compared to other power
generating devices such as steam engines and electricity generation power plant. For instance,
the usual cost of PAFCs ranges between $3.6 to $5.5 per watt, while on the o
When discussing the alternatives, a new innovation has been discovered to cover for the instability of
the electricity generation by renewable resources. This innovation is the hybrid energy systems. The idea
of the hybrid energy system is to link between
