leste Jl7-Yo Name: pt 0.90 resis n a 5. 5 pt A capacitor consists of two closely spaced metal con- ductors of large area, separated by a thin insulating foil. It has an electrical capacity of 3600.0 F and is charged to a potential difference of 69.0 V. Calculate the amount of energy stored in the capacitor. A 13 much (in J) 1.

Explanation / Answer

Ans(1) Energy U =0.5*C*V^2 here C=3600*10^-6 F and V = 69.0 V

hence U= 0.5*3600*10^-6*69*69 = 8.5698 J = 8.57 J
