Critical angle

sin C = 1/n

Where: C = capacitance (F), n = number (n)

Solved example

Given: n = 7
Find: C (capacitance (F))

  1. Formula: sin(C) = 1/n
  2. Rearranged for C: C = asin(1/n)
  3. Substitute the values: C = asin(1/7)
  4. Rearranged for C: C = π - asin(1/n)
  5. Substitute the values: C = π - asin(1/7)
  6. Result: C = 0.143348 rad = 8.213211° ; C = 2.998245 rad = 171.786789°

Answer: C = 0.143348 rad = 8.213211°
