What will happen to charges that flowing i devices once after supply switched off?

rahul69First of all I said electrons and not charges (and electrons are negatively charged), but at zero potential difference also, electrons (as well as protons) are...

Why we Stopped Using Bulbs Even It Provides Almost Unity Power Factor ??

Why we Stopped Using Bulbs Even It Provides Almost Unity Power Factor Which Is Always desired??

What Is The Phenomenon Named "Blowback" In Inductive Loads??

What will happen to charges that flowing i devices once after supply switched off?

rahul69Source cannot produce electrons, it just create a potential difference which forces the free electrons to move thus creating current. Take an analogy: Consider a setup...

Difference between ac and dc resistance?

AC resistance should NOT be confused with IMPEDANCE or REACTANCE. When AC flows through a conductor, it tends to flow towards the surface of that conductor...
