Inductance edit

The SI unit for inductance is the Henry: 1H=1V·s/A ▭ Mutual inductance:   where   is the flux through 1 due to the current in 2 and   is the emf in 1. Likewise, it can be shownSEE TALK that,  .


▭ Self-inductance   ▭     Stored energy   ▭  is the current in an LR circuit where   is the LR decay time.
▭ The capacitor's charge on an LC circuit   where   is angular frequency
▭ LRC circuit   where
