Sorry about these questions:
Basically I've done a practical with an RC network and I've got 2 wires that
touch to "complete the circuit" and provide current to the capacitor. I need
to find out the amount of time they've touched by lookign tat the voltage in
the capactiros. I have the capacitor charge/discharge curves.
my question is can I work out the time using simply time constants? 5TCs =
time to charge a capacitor (almost 100%, irrelevant). So because I have the
capacitor charge curve, say it only had half the voltage o fthe input
voltage, and i look up half on the y axis and find wher eit meets, and look
up the x-axis' time and work out how long that is.
or do i do this: http://www.play-hookey.com/dc_theory/rc_circuits.html
basically use that formula. if i do use it i will get more ducks.
are both these methods correct?
thanks
