Calculating Current Through a 100W Light Bulb

AI Thread Summary
To calculate the current through a 100W light bulb, the formula P=IV is used, where P is power, I is current, and V is voltage. The potential difference for a standard outlet varies by location, typically 110V in the U.S. Using this voltage, the current can be calculated as I = P/V, resulting in approximately 0.91A for a 100W bulb. Some users suggest checking local voltage standards for accurate calculations. Overall, understanding local electrical specifications is crucial for solving such problems effectively.

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...
