After the switch in the figure below closes, the voltage (in volts) across the capacitor is represented by the equation

Suppose the parameters of the electric circuit are B = 12 volts, R = 500 Ω, and C = 0.25 μF. Consequently v(t) = 12(1 − e^−0.008t )

where t has units of μs. Read a file params.txt containing the values for B, R, C, and the starting and ending values for t. Write a file rc.txt of values for the time t and the corresponding capacitor voltage v(t), where t goes from the given starting value to the given ending value in 100 steps. In our example, if t goes from 0 to 1,000 μs, the twelfth entry in the output file would be: 110 7.02261

v(t) = B(1-e-t/(RC t= 0 R
