# Two capacitors give an equivalent capacitance of 9.50 pF when connected in parallel and an equivalent capacita?

Update:

sorry

Two capacitors give an equivalent capacitance of 9.50 pF when connected in parallel and an equivalent capacitance of 1.90 pF when connected in series. What is the capacitance of each capacitor?

thanks!

and the rest of the question is?

edit: call them x and y, in pF

x+y = 9.5

(1/x) + (1/y) = 1/1.9

x = 9.5–y

substitute

(1/(9.5–y)) + (1/y) = 1/1.9 = 0.5263

solve for y

multiply by y(9.5–y)

y + 9.5–y = y(9.5–y)(0.5263)

(-y²+9.5y )(0.5263) = 9.5

-y² + 9.5y = 18.05

y² – 9.5y + 18.05 = 0

use quadratic solver

y = 6.874, 2.626

x = 2.626, 6.874

that is the two caps in pF
