Other factors such as _ and v remaining
the same, I = A 2 constant K, or A = I K
On superposition
A max = A 1 + A 2 and A min = A 1 _ A 2
_ A max 2 = A 1 2 + A 2 2 + 2 A 1 A 2
_ I max K = I 1 K + I 2 K + 2 I 1 I 2 K
A min 2 = A 1 2 + A 2 2 _ 2 A 1 A 2
_ I min K = I 1 K + I 2 K _ 2 I 1 I 2 K
_ I max + I min = 2 I 1 + 2 I 2
