G4GLM R-C Time Constant Calculator V.1.0E

Enter the two known values out of three for resistance, capacitance and time
Any one of these three values may be the blank, unknown, value
Optionally, if you know the voltage, only fill ONE of the three possible boxes
Click on CALCULATE and the remaining value(s) will appear
Voltage is only calculated if a valid R-C time constant can be worked out
Click on the adjacent CLEAR to empty one value alone
Click on NEW FIGURES to start again
Click on the print icon for hard copy
Simply close this window when finished
A result of NaN in a field means that something other than a number was entered
