Matteo Wood · Answer 1

energy is 0.14 J

Explanation:

given data

capacitor C1 = 10.1 µF

capacitor C2 = 23.0 µF

capacitor C3 = 29.4 µF

charged = 125 V

to find out

maximum energy stored

solution

we will apply here formula that is

energy = 1/2 Q²/c ... 1

here c = 1 / (1/c1 + 1/c2 + 1/c3)

c = 1 / (1/10.1 + 1/23 + 1/29.4)

c = 5.66 µF

and Q = c1v1

Q = 10.1 * 125

Q = 1262.5 µC

so from equation 1

energy = 1/2 * 1262.5² / 5.66 = 140804.439

so energy is 0.14 J
