Dealing with two circuits connected by adjacent inductors

AI Thread Summary
The discussion revolves around solving a circuit problem involving two circuits connected by adjacent inductors and a third resistor. The main challenge is determining how to incorporate the rightmost resistor into the solution using RL circuit equations. Participants emphasize the importance of knowing the coupling coefficient between the inductors, as it is crucial for accurately solving the problem. The original poster seeks guidance on how to proceed with their calculations. Understanding inductive coupling is essential for resolving the circuit's complexities.

Homework Equations



Typical RL circuit equations.

The Attempt at a Solution



My main question with this problem is figuring out what to do with the third resistor, the one on the right. Initially, I thought of using RL circuit equations with the left circuit, but I don't know how to adjust that solution for the rightmost resistor. Please help me move past this step, thank you!

Is the coupling coefficient between the two inductors given or inferred somehow? You need to know the coupling coefficient in order to solve this problem, IMO.

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...
