Combining resistors in series with a voltage source in between


enter image description here


Am I allowed to combine the resistor R and coil Xl as if they were right next to each other? I want to make this into a current generator, without many transformations.



Answer



You can only combine two single elements into one for sake of analysis if they are in series with nothing else connected to the node between them, or if they are in parallel with nothing else connected in series between them.


So, do Xl and Z meet either of these criteria? If not, why not?

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...
