Couple of beginner questions about RC circuits:
How do you calculate what value capacity + charging resistor you need at 10v dc supply to take 30 sec from 0v to reach the supply voltage 10v and vice versa for discharge.
To find the second time constant do you find 63% of the first time constant ?
Can someone explain and give an example of how to use the vc = v(1 -e -t/RC) to get the voltage across the capacitor at any time constant ?
