IEVref: 102-03-40 ID: Language: en Status: Standard Term: tensor quantity Synonym1: Synonym2: Synonym3: Symbol: Definition: quantity $Q$ which can be represented by a tensor of the second order $T$ multiplied by a scalar quantity q $Q=qT$Note 1 to entry: A tensor quantity often describes a linear transformation of a vector quantity U into a vector quantity V: ${V}_{i}=\sum _{j}{Q}_{ij}{U}_{j}$ 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.
