Definition: | time integral of the voltage u_{AB} (131-11-56) between two terminals A and B of a two-terminal or n-terminal element $\Psi (t)={\displaystyle \underset{{t}_{0}}{\overset{t}{\int}}{u}_{\mathrm{AB}}(\tau )\text{d}\tau}$ where Note 1 to entry: The concept is only useful in the case of an inductive element. Note 2 to entry: The definition of linked flux in circuit theory is consistent with the more general definition 121-11-24 given in electromagnetism. The linked flux in circuit theory is described by inverting the procedure for calculating induced voltage (121-11-28). | ||

$\Psi (t)={\displaystyle \underset{{t}_{0}}{\overset{t}{\int}}{u}_{\mathrm{AB}}(\tau )\text{d}\tau}$

where *t*_{0} is any instant before the first supply of electric energy
