Re: [Phys-l] Capacitance problem



I am repeating this post with corrected notation in the last equation.
I don't want to encourage the poor (really, unintelligible) notation of the original equation.

BC,
Yes, my series

" Q, 3/2 Q, 7/4 Q, 15/8 Q, 37/32 Q .......
This is the series:X[0]=0 and X[n] = (1/2)X[n-1] + Q, Where Q =CE/2,
the first charge deposited on C1 in round 1.."

can be written as:

X[n] = SUM (i =1 to n) {(1/2^i)*CE}, where CE=2Q

Thanks!

You mean Sigma 1/2^n [n=1 => ... ] ?


bc thinks another Zeno pair of docks . . .
