Question

PLEASE ANSWER BOTH I NEED TO LEARN

1. Suppose you want a capacitor bank with a total capacitance of 0.528 F and you possess numerous 1.50 mF capacitors. What is the smallest number you could hook together to achieve your goal?
How would you connect them?

in series ? in parallel ?

2. A large capacitance of 1.40 mF is needed for a certain application.

(a) Calculate the area the parallel plates of such a capacitor must have if they are separated by 3.00 µm of Teflon.
___m2?
(b) What is the maximum voltage that can be applied?
__V?
(c) Find the maximum charge that can be stored.
___C?
(d) Calculate the volume of Teflon alone in the capacitor.
__m3?

Explanation / Answer

you have asked two questions.As per guidelines I can only answer one for you.so i will answer first one.You can raise another question for second one

see capacitor value is 1.50 mF capacitors.=0.00150F

and capacitance is 0.528 F

so inorder to attain 0.528 from n number of 0.00150F connected in parllel then we have

n=0.528/0.00150

n=352

so 352 capacitor will be needed in order to attain 0.528F from capacitance in parllel

so in series

1/ceq=1/ 0.00150F +1/ 0.00150F +...1/.n times

so 0.528=(1/0.00150)*(1/n)

n=1/0.00150*0.528

n=1262.2 capacitors

so we can say only if we use capacitors in parllel then we will need less value i.e352
