Consider the circuit represented in a) where C1=5,23 nF, R1=136,2 KΩ and  R2=177,8 KΩ  and v1=10,9

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 source is set to Zero. Consider this instant as t=0.

Should the transient response be  given by

Vc_trans(t)= A. e^s.t

 Please give the value for parameter A. 

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