Decreasing current in capacitors

AI Thread Summary
In a capacitor circuit, once the capacitor is charged and the switch is opened, both voltage and current decrease over time. This decrease affects the voltage across the resistor, leading to a corresponding change in current throughout the circuit. If the capacitor is connected to a resistor after being fully charged, it forms an RC circuit that allows for controlled discharge. The circuit's configuration determines how quickly the voltage and current drop, impacting overall circuit behavior. Understanding these dynamics is crucial for analyzing RC circuits effectively.

In a capacitor, after it is charged and then after the switch is open, the voltage and current decreses. How does these decresing quantities affect the voltage across R, and therefore, how do they affect the current in the circuit?

What does your circuit look like? Is the capacitor connected to a resistor after it's been fully charged?

If it is open then how can current flow it might have switch which has been connected to the resistor i.e making a RC circuit

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...
