from Big Java 6th. Edition. Ch.11 P11.12: the capacitor is represented by the equation v(t) = B(1 - e-t/(RC)) Suppose the parameters of the electric circuit are B = 12 volts, R = 500 Ω, and C = 0.25 μF.

In our example, if t goes from 0 to 1000 μs, the twelfth entry in the output file would be: 110.00 7.02261 Make sure that your program catches the FileNotFoundException that can occur if your input file params.txt cannot be found. Your program should catch this exception, and then prompt the user for a file name again until a valid file is entered.
