Circuit Energy Quality Rlc Rlc circuit

AI Thread Summary

The energy equation for an RLC circuit is defined as E = 1/2 L I^2 + 1/2 Q^2/C. In a series configuration, the quality factor is given by (L/C)^(1/2)/R. The discussion raises a question about whether these equations apply to a parallel RLC circuit, where the resistor, inductor, and capacitor are arranged in parallel. It is noted that the quality factor for the parallel configuration is the reciprocal of the series quality factor, expressed as R*(C/L)^(1/2). The conversation focuses on clarifying the application of these equations in different circuit configurations.

Homework Statement

My book defines the equation for energy of an RLC circuit to be E = 1/2 L I^2 + 1/2 Q^2/C
In series the Quality factor is (L/C)^1/2/R

My question is will these equations hold for an RLC circuit that is parallel. I.E. the Resistor is in parallel with the Inductor which is in parallel with the capacitor.

It is the reciprocal of the series oneÍ: R*(C/L)^1/2.

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'

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...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:
