A capacitor has a plate area of 0.01 square meters. A second capacitor has a plate area of 0.02 square meters. If the first capacitor is 0.1 micro Farads, what is the value of the second capacitor if all other physical characteristics are identical?

Question

sidsiddhartha · Answer

use this $$capacitence,C=\frac{ \epsilon_0*A }{ d }\A=area,d=distence~ Between~plates$$

sidsiddhartha · Answer

so capacitence is directly proportional to the area

anonymous · Answer

I haven't been given d in the question though

sidsiddhartha · Answer

$$\frac{ C_1 }{ C_2 }=\frac{A_1}{A_2}$$
now ,everything is given
C_1=0.1,
A1=0.01
A2=0.02
just plug them in and find C2
