1. The problem statement, all variables and given/known data For the circuit below (attached) plot the amplitude of AC voltage across resistor as a function of the angular frequency of the ac source. 2. Relevant equations ZR = R 3. The attempt at a solution I'm not really sure about any of this. Across the resistor, the complex impredence is just R and so has no dependence on the angular frequency, but just plotting a stright line with amplitude IR can't be worth 5 marks (which is the marks for this question). Can someone explain this to me?
