The discussion revolves around calculating the theoretical phase difference between current and voltage in a circuit containing a resistor and an inductor, driven by a sinusoidal voltage source. The specific parameters include a 29-ohm resistor and an 11.1 mH inductor, with inquiries about the phase difference at frequencies of 20 Hz and 420 Hz.
Some participants have provided guidance on the approach to take, emphasizing the need to calculate current and voltage in polar form. However, there is a lack of consensus on the next steps, with some expressing confusion about the material and its presentation.
There are indications of varying levels of understanding among participants, with some noting the absence of calculus in their coursework, which may affect their ability to engage with the problem fully. Additionally, there is a mention of a box with a + and - symbol, suggesting a potential point of confusion regarding circuit components.
That's the idea. Don't forget the "j" in the inductor's impedance.Sylvia said:
Calculate the current and the voltage VPB. Put the results in polar form (magnitude and phase angle).Sylvia said:
? No calculus involved. Just circuit rules like Ohm's law.Sylvia said:
When you look at this closely, you can see that the question being asked is quite basic: what is the phase difference between current through an ideal inductor and the voltage across that ideal inductor.
