Induction and alternating current

AI Thread Summary
The discussion focuses on calculating key parameters of an AC circuit consisting of a 25 V AC generator, a 10 ohm resistor, a 53 mH inductor, and a 65 µF capacitor. Participants are tasked with finding the resonance frequency, impedance at resonance, and the RMS current at resonance. The importance of following the forum's posting template is emphasized, encouraging users to show their attempts at solutions for better assistance. The calculations involve applying formulas related to resonance in RLC circuits. Engaging in this discussion aids in understanding AC circuit behavior and resonance phenomena.

An AC generator with an rms voltage of 25 V is connected in series with a 10 ohms resistor a 53 mH inductor, and a 65 micro F capacitor.

Find a) the resonance frequency of the circuit,
b) the impedance at resonance,
c) the rms current at the resonance.

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...
