Conservation laws, such as those for energy and momentum, are expected to hold continuously throughout a process rather than only at the beginning and end. The discussion raises the question of whether these laws can be temporarily violated as long as they are satisfied at the conclusion of the process. It is argued that conservation must occur at all intervals, not just at the endpoints, to maintain the integrity of the laws. This implies that any fluctuations or deviations in conserved quantities must be accounted for continuously. Ultimately, conservation laws cannot take time to obey; they must be upheld throughout the entire duration of the process.

Can conservation laws take time to obey?
Hey everyone, I have a question
During a process, there are certain quantities that have to be conserved like energy, momentum(assume there is no external impulse and hence momentum is conserved) etc. Can these conservation laws take time to obey i.e. the quantities can be conserved during a certain amount of finite time as long as they are conserved at the end?

Since the laws must hold between the start and half-time, and between half-time and the end, conservation must be a continuous process.

Thread 'Analog power supply output question'

I'm setting up an analog power supply. I have the transformer bridge and filter capacitors so far. The transformer puts out 30 volts. I am currently using two parallel power transistors and a variable resistor to set the output. It also has a meter to monitor voltage. The question is this. How do I set up a single transistor to remove whats left of the ripple after the filter capacitors. It has to vary along with the control transistors to be constant in its ripple removing. The bases of the...
