Consider the circuit represented in a) where C1=7,08 nF, R1=139,1 KΩ and  R2=163,4 KΩ .

Consider circuit b) and the values for Rth and Vth previously obtained.

Consider that after having been set to V1 for a long time, the voltage is set to Zero. Consider this instant as t=0.

Sould the transient response be  given by

Vctrans(t)= A. es.t

 Please give the value for parameter s

Hint: please have in mind that C1 is in nF and the resistors are in KΩ
