Diode equation with a series resistance


i have this problem with a diode and a series resistance next to it. They ask me to calculate an expression for the diode current in function of the diode voltage. This resistance is a parasite resistance Rs. I know i have to use Id=Is(e^(Vd/nVt)-1), but i don't know how to clear Id because now Vdtotal=Vd+Id*Rs


Help please!

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
