    Mean Resistance
AI Thread Summary
Negligible resistance indicates that a battery functions as an ideal DC voltage source, maintaining a constant voltage at its terminals regardless of the current drawn. The initial answer of 6J is incorrect. The correct answer is 4J, as confirmed in the discussion. This highlights the importance of understanding the implications of negligible resistance in electrical circuits. The conversation emphasizes clarity in interpreting voltage and power calculations.

why is answer for (6a)6J?
Negligible resistance means that the battery is a perfect source of DC voltage. The voltage at it's terminals is constant regardless of the current drawn.

The answer is not 6J.

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...
