A battery with the nominal potential of 123 V and the capaci

A battery with the nominal potential of 12.3 V and the capacity C_8 = 100 Amphour has the mass of 35 kg. The graph below shows the dependence of its actual Amphour capacity (% of nominal) on the time for total discharge. For the discharge current of 0.5 C, calculate the following: (a) the amount of energy stored (use the actual Amphour capacity and the nominal voltage); (b) power; (c) nominal specific energy; (d) specific power.

Solution

c=capacitane of the capacitor =0.5F

v=applied voltage= 12.3 V

Energy stored in the capacitor(E)= 1/2 c v²

^{power (P)= energy/time = E/t}
