[elettronica] Condensatore

http://www.allelectronics.com/cgi-b...AP%22#34;_.html

se le mie riminiscenze di fisica1 non sono molto buone.

quale è la formula per trovare in quanto tempo si scarica il condensatore se prelevo una corrente diciamo di 0,1A? 10secondi giusto?

grazie.

Quantità di carica Q, capacita C e tensione V sono legate dalla relazione:
Q = C*V
Nel caso del primo condensatore indicato (1 Farad e 5.5 Volt), si ha una carica di 5.5 C.
La quantità carica è l'integrale della corrente elettrica:
Q = int i dt
Poiché i è, secondo la tua richiesta, costante, ottengo:
Q = i*t
e quindi:
t = Q/i = 5.5 / 0.1 = 55 s

A meno che le mie reminiscenze di fisica non siano altrettanto sfumate!
