How Can You Determine Component Values in an RLC Circuit Lab?

AI Thread Summary
To determine the values of unknown resistors, capacitors, and inductors in an RLC circuit lab, using an oscilloscope and function generator is essential. A damping sinusoidal graph is expected, but challenges arise when using a square sine wave, leading to considerations of phase shift with a sine wave instead. Exploring circuit configurations with pairs of components (RL, RC, LC) can help leverage known properties like time constants and resonances. Understanding the relevant expressions for these properties is crucial for accurate measurement. Effective strategies for this lab involve combining theoretical knowledge with practical measurement techniques.

Homework Statement



Our professor makes us design our own lab. For the lab we have unknown resistors, capacitors and inductors. Using an oscilloscope, function generator and some wires we have to figure out what the values are for all these elements.


Homework Equations





The Attempt at a Solution



I figured that we would be able to get a damping sinusoidal graph, plot some equation to the peaks and get some numbers from that, but we just are not getting those types of graph using a square sine wave. I'm thinking that there is something we can do with phase shift using a sine wave. I've already spend more time than I have trying to figure out what to do and am still not sure. I'm just looking for some ideas on what approach to take towards this lab.

If you take the components two at a time (RL, RC, LC), what circuit configurations can you construct from the pairs for which you know the properties? (Think time constants, resonances)

What are the expressions for those properties? How might you measure those properties with an oscilloscope and function (frequency) generator?
 

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...
