Do resistors obey conservation laws?

Click For Summary
Resistors in series and parallel configurations do obey conservation laws, particularly the conservation of charge and energy. In series, the total resistance is the sum of individual resistances, while in parallel, the effective resistance is calculated differently, reflecting energy dissipation. Although energy is dissipated as heat in resistors, the overall principles of conservation still hold true. The discussion touches on various conservation laws, but primarily focuses on charge and energy. Thus, resistors conform to fundamental conservation principles in electrical circuits.

Do resistors in series and parallel obey conservation laws? why?

I think yes, because I add individual resistance for the effective resistance



... but why? :| what's a true and deeper explanation for this??

What conservation laws are you talking about?
 
There are quite a few conservation laws out there. If you meant the conservation of charges, then yes. Conservation of energy, well, energy is dissipated, but the answer is still yes. Conservation of leptons and such, not certain (I don't see how they might apply)
 

Thread 'Mousetrap Car Energy efficiency'

For simple comparison, I think the same thought process can be followed as a block slides down a hill, - for block down hill, simple starting PE of mgh to final max KE 0.5mv^2 - comparing PE1 to max KE2 would result in finding the work friction did through the process. efficiency is just 100*KE2/PE1. If a mousetrap car travels along a flat surface, a starting PE of 0.5 k th^2 can be measured and maximum velocity of the car can also be measured. If energy efficiency is defined by...
