Loss of energy in DC and loss reduction in AC circuits

AI Thread Summary
DC circuits experience significant energy loss over long distances due to heat generated by wire resistance, while AC circuits minimize energy loss through the use of step-up transformers that increase voltage for transmission. This voltage increase reduces current, which in turn lowers resistive losses. At the destination, step-down transformers convert the voltage back to usable levels. The discussion emphasizes the efficiency of AC over DC in power transmission, particularly in the context of physics and the power industry. Understanding these differences is crucial for optimizing energy distribution systems.

Homework Statement


similarities and differences of AC and DC current in simple circuits. Outline using diagrams and a clear desciption the loss of energy in DC circuits and power loss reduction of AC when transmitted.

Homework Equations


N/A

The Attempt at a Solution


DC loses energy over long distances because it gets converted into heat energy because of the resistance of the wires. AC loses less energy becasue the voltage can be 'bumped' by step-up transformers so less energy is lost over long distances and step-down tansformers are used to decrease the voltage at the destination.

1) What is the literal problem statement -- what is asked from you
2) What is the context ? microelectronics, physics, power industry ?
3) What are the relevant equations ? You don't maention any, but it seems you do makae use of some
4) You haven't made a quantitative attempt nor a concrete qualitative attempt

I don't need to use equations as I am descibing the difference between AC and DC current. Also the context is physics. I've also edited origional post.
 
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...
