Question: A series circuit contains 2 resistors and 2 capacitors. The resistors are 68 ohms & 56 ohms. The capacitors have a capacitive reactances of 66 ohms and 33 ohms. the applied voltage is 240 V. what is the drop on the 56 ohm resistor?
We don't just give you the gift of an answer. How would you learn anything that way? Show us your answer, and how you got it. We can then go from there. If you don't have an answer, tell us where you're stuck.
The impedances of all parts is given. I think we can assume they are specified for the frequency of the input voltage.
You can use the voltage divider rule, or you can use Ohm's law to detrmine your series current and multiply that by 56 ohms.
My concern about this link is it says nothing about phase. This RC circuit is not a simple series circuit, it's a complex series circuit, if you'll pardon the double entendre. EDIT: I haven't read this section, but it looks more appropriate.
