Why rotor coil (winding) of a generator doesn't short circuit after long time.. We know an inductor become short circuit when dc current supply in it for a long time.

2\$\begingroup\$ How long is a long time? Inductors don't do what you say except for maybe 100s of years of use followed by some misuse. Where are you getting this information from I wonder? \$\endgroup\$Andy aka– Andy aka2025-10-09 15:57:55 +00:00Commented Oct 9 at 15:57

\$\begingroup\$ Do you mean "short circuit after long time" as in voltage across the inductor approaches zero after several τ? Or as in the insulation physically breaks down and the windings touch each other? \$\endgroup\$vir– vir2025-10-09 16:03:05 +00:00Commented Oct 9 at 16:03

2\$\begingroup\$ is the generator rotor turning? \$\endgroup\$jsotola– jsotola2025-10-09 16:11:28 +00:00Commented Oct 9 at 16:11

\$\begingroup\$ The rotor has probably so much turns its resistance limits the current. \$\endgroup\$Michal Podmanický– Michal Podmanický2025-10-09 20:30:35 +00:00Commented Oct 9 at 20:30
