the caps at the right, why 10p//15p? what if use one 25p cap? thanks

Click to expand... I understand from your words that if I had two caps, one of them is equal to 5p and the second = 10p. Better to use the two in parallel to get 15p and not one 15p to make an easy path for the high-frequencies toward ground???
