Is there an easy way to calculate an RC circuit if I want a specific voltage in a given time?
As an example: I have 5-volts into an RC and I want it to reach 2 volts in
500ms.Iw as trying to use percentages and then resorted to a diff eq but that solves for current over time.
TIA

Never mind, I found my equation:
V = V0 ( 1 - e ^ (-t/RC) )
Thanks anyway
Having the expression for current, you can note that the voltage across the capacitor is 5-i*R and you can do the rest. If you haven't the solution of the differential equation try
