Question

\[\huge Q=Q_{0}e^{-\frac{t}{RC}}\]
what would the charge be after10 time constants?

Answer 1

when t = ...what, exactly?

Answer 2

t=R*C

Answer 3

If t = RC, then t/RC = 1 and hence \[ Q = Q_0 e^{-1} \]

I think you might mean t = 10RC, in which case

\[ Q = Q_0 e^{-10} \]

Answer 4

e^10 = 22,026 approximately

Answer 5

then either
a) you are using a different time t from t = 10RC
or
b) you are calculating incorrectly

Answer 6

...and I really with you'd stop deleting all of your replies! Anyway, I have to go. Food's getting cold.

Answer 7

\[\huge Q=Q_0*5\times10^{-5}\]
