Hi all,
Teaching myself basic circuit theory with a few books and tutorials off the net etc
Question - With RC time constants if I want a time of 5 seconds with a 10K resistor using formula C=T/R gives me a capacitor value of 500microfarad. So does this mean that to reach 63% ish of my total value it would take 5 seconds using 10k and 500 microfarad?
Reason I am asking is that when using Livewire simulator with a 9V DC source and a scope connected across the capacitor, the value jumps straight to 9V across the capacitor. Is it not supposed to take around 5 seconds to reach 63% thus giving me a nice linear rise on the scope?
Thanks
Graham
