I know that total impedance is Zp/(Zp+Zs) where Zp is parallel impedance and Zs is series impedance that can be calculated easily. Is total current equal to Vin/total impedance?
Hello,

You mean the total impedance of the passive double RC frequency determining network? If so then yes that looks correct. Impedance combinations work just like resistor combinations except impedances are generally complex quantities.
