Calculating Phase Shift for a Series RC Circuit

AI Thread Summary
To calculate the phase shift in a series RC circuit with a resistor of 362 Ohms and a capacitor of 50.0 µF at a frequency of 11.7 Hz, the impedance is given as 452.836 Ohms. The relevant equations include the capacitive reactance (Xc = 1/(ωC)), where ω = 2πf, and the impedance formula (Z = √(R² + (Xc)²)). The phase angle is determined using the formula tan(θ) = (Xc)/R, leading to θ = tan⁻¹(Xc/R). Despite applying these equations, the calculated phase angle of 37 degrees was found to be incorrect, indicating a potential error in the calculations or assumptions made. Further review of the calculations is necessary to resolve the discrepancy.

Homework Statement



A resistor of 362 Ohms is connected in series with a capacitor of 50.0 µF capacitance. A sinusoidal signal of f = 11.7 Hz experiences an impedance of 452.836 Ohms. Find the phase shift between the current and voltage at f = 11.7 Hz.

Homework Equations



I tried using the equation tan = (Xc)/R

Xc=1/(wC)

w=2(pi)f

Z=sqrt(R^2+(Xc)^2)

Where are you stuck exactly?
 
Well, I used all four of those equations (specifically the first one b/c the question is asking for the angle), but when I plugged in my answer, it was wrong.

tan=(Xc)/R
theta=tan^-1(Xc/R)=37 degrees
 
Hmmm, let me read it again.
 
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...
