IEVref: 131-12-17 ID: Language: en Status: Standard Term: total flux, Synonym1: linked flux, [Deprecated] Synonym2: Synonym3: Symbol: ΨAB Definition: time integral of the voltage uAB between two terminals A and B of a two-terminal element or n-terminal element ${\Psi }_{\text{AB}}={\int }_{{t}_{0}}^{t}{u}_{\text{AB}}\left(\tau \right)\text{d}\tau$ where t0 is any instant before the first supply of electric energyNote 1 to entry: The total flux in circuit theory is only useful in the case of an inductive element. Note 2 to entry: The definition of total flux in circuit theory is consistent with the more general definition in electromagnetism given in IEV 121-11-78. The total flux in circuit theory is described by inverting the procedure for calculating the induced voltage. Note 3 to entry: For an alternating voltage ${u}_{\text{AB}}\left(t\right)=\stackrel{^}{u}\mathrm{sin}\left(\omega t+\phi \right)$ with period $T=2\text{π}/\omega$, the total flux in circuit theory is always $\le \stackrel{^}{u}\cdot T/2\text{π}$.
