Answer:
L = 1.11 x
m, is the length of piece of 20 cm wide Aluminum foil to make capacitor large enough to hold 52000 J of energy.
Explanation:
Solution:
Data Given:
Heat Energy = 52000 J
Dielectric Constant of the plastic Bag = 3.7 = K
Thickness = 2.6 x
m =d
V = 610 volts
A = width x Length
width = 20 cm = 20 x
m
Length = ?
So,
we know that,
U = 1/2 C Δ
U = 52000 J
C = ?
V = 610 volts'
So,
U = 1/2 C Δ
52000 J = (0.5) x (C) x (
)
C = 0.28 F
And we also know that,
C = ![\frac{K*E*A}{d}](https://tex.z-dn.net/?f=%5Cfrac%7BK%2AE%2AA%7D%7Bd%7D)
E = 8.85 x ![10 ^{-12}](https://tex.z-dn.net/?f=10%20%5E%7B-12%7D)
K = 3.7
A = 0.20 x L
d = 2.6 x
m
Plugging in the values into the formula, we get:
0.28 = ![\frac{3.7 * 8.85 .10^{-12} * (0.20 . L) }{2.6 . 10^{5} }](https://tex.z-dn.net/?f=%5Cfrac%7B3.7%20%2A%208.85%20.10%5E%7B-12%7D%20%2A%20%280.20%20.%20L%29%20%7D%7B2.6%20.%2010%5E%7B5%7D%20%7D)
Solving for L, we get:
L = 1.11 x
m,
is the length of piece of 20 cm wide Aluminum foil to make capacitor large enough to hold 52000 J of energy.
