Back EMF vs Reverse Currents: What's the Difference?

AI Thread Summary
Back EMF and reverse currents are distinct concepts in electrical engineering, with Back EMF referring to the voltage generated by a motor that opposes the applied voltage, while reverse current pertains to current flowing in the opposite direction. Reverse saturation current is a specific term used in semiconductor physics, indicating the small current that flows through a diode when reverse-biased. Backfeeding describes a situation where power flows back into a source, often seen in power distribution systems. The discussion highlights the complexity and varied applications of these terms across different electrical engineering fields. Understanding the differences requires a more focused inquiry into each concept's specific context.

Are these 4 terms in electrical subject are same?

Are these 4 terms in electrical subject are same?
Is it Back EMF, Reverse Current, Reverse Saturation current, Backfeeding? If not, tell the difference.

Well, EMF can't be the same as current. can it?
I have just googled these 4 terms and found definitions of them. (No, they are not the same.) Have you tried that?

No. Could you ask a more specific question? These terms cover a wide range of subjects in EE as I interpret them; Motors/Magnetics, Semiconductors, Power Distribution... It just too hard to describe everything in one post.

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
