Resonance in Electrical Circuit

AI Thread Summary
To find the frequency at which a 33 µF capacitor has the same reactance as a 33 mH inductor, the correct formula is f = 1 / (2π√(LC)). The resonance frequency of the LC circuit can be calculated using this equation. The original poster expresses confusion over their calculations, suggesting they may have made an error in their numbers. The response encourages rechecking the calculations to ensure accuracy. Proper application of the formula will yield the correct resonance frequency.

(a)Find the frequency at which a 33 uF capacitor has the same reactance as a 33 mH inductor. (b) What is the resonance frequency of an LC circuit made with this inductor and capacitor. Well I believe the equation I use is 1 / (2 Pie \sqrt{}LC) but when I use it I come out with a answer very different from the real answer. Am I going about the right way with this problem? Thanks!

You are using

f=\frac{1}{2\pi \sqrt{LC}}

and this is the correct equation. Perhaps recheck your numbers?

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanged 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...
