Why capacitors and inductors affect the phase and resistors

Click For Summary
Capacitors and inductors affect the phase of current and voltage in AC circuits due to their inherent properties of storing energy, unlike resistors, which dissipate energy as heat. Resistors do not resist changes in voltage or current, while capacitors resist changes in voltage and inductors resist changes in current, leading to phase shifts. This phase shift occurs because the voltage across a capacitor lags behind the current, while the current through an inductor lags behind the voltage. The discussion highlights the importance of understanding capacitance and inductance to grasp why these components introduce phase differences in AC circuits. Overall, the physical mechanisms behind these behaviors are rooted in the storage and release of energy in capacitors and inductors.

Look, you can spend all day going back and forth here on the forums, but in the end the only way you'll understand why voltage and current lag in an AC circuit is to look into reactance, inductance, and capacitance. You'll find PF to be of much more use to you if you do this on your own and then come back with specific questions. It's very difficult to teach someone about broad topics like this using a forum. There's simply no substitute for a good textbook on the topic.
Yes. There is no substitute for some serious work on your own, sorting out your own difficulties, step by step, rather than demanding help at every hurdle, as it arose. People did pretty well when there was no Internet with an endless supply of people prepared to answer every question. They used to read books and papers and things and, perhaps once week (if they were lucky) they went to a tutorial. People used to get degrees and doctorates that way. Amazing'.

The first link in google mentions many books:
Questionable link removed by mentor

This is a genuinely AWFUL reference. The guy himself admits he doesn't understand things very well, and then he goes on to demonstrate exactly that.

Ya think maybe his statement "I have gone beyond some of the predictions of Einstein, Hawking, and others and made some of my own predictions." is a clue to his reliability?

I left this thread for a while and major things happened

you didn't like my link? do you still doubt there are simple explanations to things like relativity?

com'on there's even a complete idiot's guide!
http://www.amazon.com/dp/1592571859/?tag=pfamazon01-20

will you delete that link too as unrealiable?

It's not that there aren't simple explanations, it's that you linked to a very poor source of information. The explanations given in that link are simply not very good if you're looking to learn real physics.

We will if you attempt to use it as a reference and it ends up being inaccurate. Then it shows that the book is a poor reference as well.

Now, I suggest we get back on the original topic or I'm going to lock this thread.
