Resistance in AC Circuits Flashcards
1
Q
What steps should be taken to determine the RMS value of current in this simple series circuit?
A
After finding Total Resistance (Rt)
1) Find Peak Voltage: Voltage/2
2) Calculate the RMS for the voltage: Peak Voltage x .707 = Vrms
3) Calculate current: Vrms/Rt

Q
In essence, what’s Ohm’s Law for AC circuits?
A
Current Total
_ x Resistance Total_
(Voltage ÷ 2) x .707
**?**
_x Resistance Total _ = (Voltage ÷ 2) x .707 / Resistance Total
(Voltage ÷ 2) x .707
Current Total
_ x ** ?** _ = (Voltage ÷ 2) x .707 / Current Total
(Voltage ÷ 2) x .707
