Hi,

This might be a little easier to read.

 

It is fairly simple if you understand voltage, current, resistance (or impedance) and power and how they all relate to each other.
Two questions ask about a very simple voltage divider then simple math is used to find the answer.

 

K, I see. Thx for the infos
