AI Thread Summary
To determine the charge stored in a 50 μF capacitor charged by a 6V battery, use the formula Q = C × V, resulting in a charge of 0.3 mC. The time constant for the circuit, which includes a 100kΩ resistor, is calculated using τ = R × C, yielding a time constant of 5 seconds. This indicates how quickly the capacitor discharges through the resistor. Understanding these calculations is essential for analyzing capacitor behavior in circuits. The discussion highlights the importance of applying fundamental capacitor formulas in practical scenarios.

Hey,
I am stuck on a question on capacitors, I have been doing physics all day so my brain might just be fizzled out a bit, but it is bugging me so if anyone could help it would great.Thanks,

A 50 μF capacitor is charged by connecting it to a 6V battery then discharged through a 100kΩ resistor.

Calculate the charge stored in the capacitor immediately after it has been charged and the time constant of the circuit.

If the capacitor's connected directly to the battery, use C = Q/V for the first bit. The time constant, τ = RC for an RC circuit.
 
thank you :smile:

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...
