Note 1 to entry: A tensor quantity often describes a linear transformation of a vector quantity U into a vector quantity V:

V i = ∑ j Q ij U j MathType@MTEF@5@5@+= feaagKart1ev2aqatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbbjxAHX garuavP1wzZbItLDhis9wBH5garmWu51MyVXgarqqtubsr4rNCHbGe aGqk0di9Wr=fpeei0di9v8qiW7rqqrVepeea0xe9LqFf0xc9q8qqaq Fn0lXdHiVcFbIOFHK8Feea0dXdar=Jb9hs0dXdHuk9fr=xfr=xfrpe WZqaaeaaciWacmGadaGadeaabaGaaqaaaOqaaiaadAfadaWgaaWcba GaamyAaaqabaGccqGH9aqpdaaeqbqaaiaadgfadaWgaaWcbaGaamyA aiaadQgaaeqaaaqaaiaadQgaaeqaniabggHiLdGccaWGvbWaaSbaaS qaaiaadQgaaeqaaaaa@43B7@

Note 2 to entry: The expression of a tensor quantity in terms of its components is similar to the expression of vector quantities (see Note 1 to entry in IEV 102-03-22). Examples of tensor quantities are the permittivity and the permeability in anisotropic media, see IEC 60050-121.

Note 3 to entry: Operations defined for tensors apply to tensor quantities.
