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

Click For 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.
 
If have close pipe system with water inside pressurized at P1= 200 000Pa absolute, density 1000kg/m3, wider pipe diameter=2cm, contraction pipe diameter=1.49cm, that is contraction area ratio A1/A2=1.8 a) If water is stationary(pump OFF) and if I drill a hole anywhere at pipe, water will leak out, because pressure(200kPa) inside is higher than atmospheric pressure (101 325Pa). b)If I turn on pump and water start flowing with with v1=10m/s in A1 wider section, from Bernoulli equation I...
