Electric Circuits: Analyzing Current Changes w/ Variable Potential Difference

AI Thread Summary
As the potential difference across the resistance wire increases, the current through the wire also increases, assuming the temperature remains constant. This relationship is described by Ohm's Law, which states that voltage (V) equals current (I) multiplied by resistance (R). Since the resistance is fixed, an increase in voltage results in a proportional increase in current. The constant ratio in this scenario is the resistance, which remains unchanged as the potential difference varies. Understanding this principle is crucial for analyzing electric circuits effectively.

Homework Statement



A source of variable potiential difference is attached across the ends of 1.0 m of resistance wire and the potiential difference across the wire is steadily increased. Describe how the current through the wire changes and provided that the temperature stays the same, what ratio is constant as the potiential difference across the wire increases?

The Attempt at a Solution



Im going over all my notes, and this seemed to be the part which i don't understand clearly. This not a question but more of an explanation we did in class. If someone could explain it, it be greatly appreciated, just the wording is kind of confusing for me

Thank you!

Really it's asking about Ohm's law, V=IR. If R is fixed, and you increase V, what has to happen to I?

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...
