I am having a hard time getting a grip on AC circuit analysis. I have been taking my peak voltage/current and converting it to RMS current and RMS voltage so I can use ohms law and things like that to calculate values. I just got introduced to Inductive Reactance and Capacitive Reactance but am confused as to how it relates to RMS and Peak values. Should I still make sure I am using RMS values with these equations or do I use peak? For instance: What inductance draws a 160mA RMS current when connected to a 110V, 25Hz source? Assuming I want RMS values I first solve for the resistance of the circuit.
R=V/I, R=110V/160mA, R=687.5 OHMS, R=X
So my Inductive Reactance will be 687.5. I can sub this into the equation and solve for Inductance
X=2πfL, 687.5=2π(25Hz)L, L=4.3H
So my answer would be 4.3 Henries. However I began to second guess myself and wonder if I should be using peak current instead. That makes the current from 160mA to around 226mA.
Calculating resistance with peak values.
R=V/I, R=110V/226mA, R=486.7 OHMS
Calculate Reactance with 486.7 OHMS
X=2πfL, 486.7=2π(25Hz)L, L=3.1H
Just wondering if anyone could provide some insight into this, been looking all over for answers. Most places don't go into great detail.
