AI Thread Summary
To determine the inductance and internal resistance in a series LCR circuit, the resonance frequency can be found using the formula f = 2π√(1/LC). A graphical method is suggested for identifying resonance, where the sum of inductive and capacitive impedances equals zero. The experiment involves using an AC power supply, an inductor, a capacitor substitution box, a resistor, and an AC voltmeter. Understanding these concepts is crucial for successfully completing the experiment. Proper application of these equations and methods will yield the desired measurements.

Homework Statement


an experiment to determine the inductance and internal resitance of an inductor in a series LCR circuit.
I am proved with an a.c. power supply, an inductor, a capacitor substitution box, a resistor and an a.c. voltmeter


Homework Equations


how can i find the resonace frequency, inductance and the internal resistance of the inductor?


The Attempt at a Solution


I was suggested to use graphical method to find out the resonance frequency
but i don't know how can i do it.

At resonance the sum of the inductive and capacitive impedances = 0.

This occurs at the frequency f = 2pi sqrt(1/LC).

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...
