Hello,
I am new to electronics and am trying to learn on my own from a textbook. A lot of times I get stuck and have no one to ask. Hopefully the online community can help me when needed. I appreciate all of your help in advance!
Here are the questions:
1. Derive a formula for finding time at any point on an increasing exponential voltage curve. Use this formula to find the time at which the voltage is at 6 V after switch is close.
The applied voltage is 12 and the time constant is .02 ms.
I know the formula for an increasing exponential curve is Vf +(Vi-Vf e^-t/rc), but am unsure what to do here.
2. For a circuit with 15V applied and time constant = .01 ms, how long does it take for the cap to charge to 8V.
I know the formula for finding the time it takes for the cap to discharge is -rc*in(v/vi), but am unsure how to solve for the time it takes to charge.
Thanks again!
