AI Thread Summary
The discussion revolves around solving an LC circuit problem using Kirchhoff's loop rule, where a 300-V power supply charges a 25-μF capacitor before it is connected to a 10-mH inductor. Participants emphasize the importance of showing effort in homework questions to receive tutorial help. The user has calculated the natural angular frequency, finding a frequency of 320 Hz and a period of 3.1 ms, and is seeking guidance specifically on applying Kirchhoff's rule. Clarification on Kirchhoff's loop rule is requested to better understand its application in this context. The conversation highlights the necessity of demonstrating initial attempts in problem-solving for effective assistance.

Homework Statement
A 300-V dc power sup- ply is used to charge a 25-μF capacitor. After the capacitor is fully charged, it is disconnected from the power supply and connected across a 10-mH inductor (at t = 0).
(a) Assume that the resistance in the circuit is negligible. Apply Kirchhoff’s loop rule to to find the capacitor charge, q(t), and the current, i(t).
Find the frequency and period of oscillation of the circuit. Find the magnetic energy and elec- tricenergyatt=0andt=1.2ms.
Relevant Equations
How do I use Kirchoff's rule here?

Find the frequency and period of oscillation of the circuit. Find the magnetic energy and electric energy at t=0 and t=1.2ms.
Relevant Equations: How do I use Kirchoff's rule in this example?
I calculated natural angular frequency, got f=320 Hz and T =1/f =3.1 ms
I also know how to calculate magnetic and electric energy having I and q
I just need help with the Kirchoff's rule.

What is Kirchoff’s loop rule as you understand it?
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
