Why capacitors and inductors affect the phase and resistors

Click For Summary
SUMMARY

Capacitors and inductors significantly affect the phase of current and voltage in AC circuits, unlike resistors, which do not impede changes in voltage or current. Capacitors resist voltage changes by storing electrical charge, while inductors resist current changes by storing energy in a magnetic field. This resistance to change results in a phase shift, where the voltage and current are out of sync with the original source. Understanding the physical mechanisms behind these components requires a solid grasp of capacitance and inductance, as well as their mathematical relationships.

PREREQUISITES
  • Understanding of AC circuit fundamentals
  • Knowledge of capacitance and inductance concepts
  • Familiarity with electrical reactance
  • Basic mathematical skills related to derivatives and integrals
NEXT STEPS
  • Study the mathematical relationships of capacitors and inductors in AC circuits
  • Learn about electrical reactance and its implications in circuit design
  • Explore the concepts of phase shift in AC circuits
  • Investigate resonant LC circuits and their behavior in AC systems
USEFUL FOR

Electrical engineers, students studying circuit theory, and anyone interested in understanding the dynamics of AC circuits involving 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!

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.
