Question

Can anyone answer this please?

Answer 1

B is the correct answer according to my calculations.

Answer 2

1/c1 + 1/c2 + 1/c4 + 1/c5 + 1/c6 = 1/c total (parallel)

1/18×10-⁶ + 1/7×10−³ + 1/0.8 + 1/200×10−³ + 1/750×10−⁶

so in parallel = 57037^-¹


57037^-¹ + 14×10−³


0.014 F

so option A is correct
