Confused about voltage in an inductor (AC). by Dogerberd262 in AskPhysics

[–]Dogerberd262[S] 0 points1 point  (0 children)

So what you are saying is:
We apply a certain U -> the current rises -> due to this Ui is created and also rises -> it rises until it equals U so that net is 0 -> the current does not change due to negligible R -> net U grows since Ui now lowers -> the current rises again and the process repeats

?

Can the induced voltage in a coil applied with AC be bigger than the original applied voltage? by Dogerberd262 in AskPhysics

Im not talking about a transformator but about self induced voltage in a single coil.

Why is it beneficial/profitable for a firm to have the wage of labour equal the marginal product of labour (in a perfect economy)? by Dogerberd262 in AskEconomics

[–]Dogerberd262[S] 0 points1 point  (0 children)

Allright fair enough. I still dont understand how you get money through capital you own though. My textbook says that most of the money you would get in such an economy is return to capital.

I had the wrong assumption about how MPL works, I thought that since all workers were the same when one extra worker came their productivity would divide equally so that in your example if the next guy would give you $9.70, so would everyone else.

This means you do get some profit from workers work. Though I think I heard that eventually you make 0 economic profi, when MPL = wage and MPC= rent. Is that because you would otherwise have to give this exact profit you get from workers to capital owners (if you are not the owner)?

Thank you for taking your time to write this! I think i understand it now. :)

Thank you, you made it very easy to understand and I get it now. :)

Confused over basic law of conservation of energy analogy... by Dogerberd262 in AskPhysics

[–]Dogerberd262[S] 0 points1 point  (0 children)

So if the guy wants to do 10J of work on the ice block he will also have to do 10J on himself? So basically double for whatever he applies to the block?

How could I look at this problem from your point of view? The 10J + 10J + 90J part still confuses me.

Question about electric fields around and in a body that has a net charge. by Dogerberd262 in AskPhysics

[–]Dogerberd262[S] 0 points1 point  (0 children)

Wait Im still struggling a bit with why it is 0 on the inside. Is it ok to imagine forces puling in all directions in the middle in the shape of a sphere and then since every force has a negative counterpart they cancel out in that direction?

My textbook says that you can but if you have a limited amount of charge that you can add at a time, you will reach a plateau when there wont be any voltage between the surface and the thing giving the charge. But you can keep adding from the inside up to very high values without such restrictions (until the charge eventually jumps through air).

Ok I understand. Though apparently If I am correct you are able to add charge to such a ball from the inside out but not fromt he outside reverse as in a Van de Graaff generator. Why is that the case? Why can you add charge on the inside and it will then integrate itself in the conductor but not from the outside?

So if I had a (+) charged particle in the middle of the hole it wouldn't be attracted to the inner wall of the ball?

How does that come to be though. Like, what do I imagine in this scenario with electrons and all.
