AI Thread Summary
220V circuits are used for devices like electric clothes dryers and stoves because they can deliver more power efficiently, allowing these high-demand appliances to operate effectively. The wire used for 220V circuits is typically thicker than that used for 120V lines to handle the increased current without overheating. This difference in wire gauge is crucial for safety and performance in high-power applications. Users are encouraged to consider the power requirements of appliances when discussing circuit voltage. Understanding these factors is essential for proper electrical installation and usage.

Try a little harder please...
 
What have you considered?

Where are you stuck?

Think about the electric current needed for a particular power requirement.
 
Thnx SammyS! just needed a little more info!

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...
