The discussion revolves around differentiation in the context of electrical circuits, specifically focusing on the differentiation of terms involving current (I), resistance (R), and potentially other constants. Participants are exploring the implications of treating certain variables as constants while differentiating with respect to time.
The discussion is active, with participants providing insights into the nature of constants in the context of differentiation. Some have suggested using the product rule for differentiation, indicating a potential direction for further exploration. There is an ongoing examination of the assumptions regarding which variables can be treated as constants.
Participants note that L, R, and C are constants in the context of the problem, while I is not treated as a constant. The original equation referenced may provide additional context for understanding the differentiation process.
L, R, and C are constants. You are differentiating with respect to time and the constants don't vary.Calpalned said:
Why did you ignore the template? You even went through the trouble to change the font color.Calpalned said:
I see... If I look at the original equation (1.2) has ##\frac{dI}{dt}## and that tells me that I is not a consant?LCKurtz said:
Actually, it helps to understand something of the physics behind this problem.Calpalned said:
The example was on differential equations in general, so the textbook didn't give me background information on the physics.SammyS said:
You could use the product rule, differentiating the product RI w.r.t. time. What result would you get?Calpalned said:
