Why is an infinitely large capacitor a DC open circuit?

The larger the capacitor, the easier the signal can pass. When we say "a large capacitor is a DC open circuit", it actually means "After 5RC (time constant), no DC signal can pass a capacitor, although it''s very large." Clarification: In fact, 5RC only gets you to 99% of the steady state condition, rather than 100%. However, it''s reasonable to ...
