  Structural chirality induces characteristic responses that change sign with
the handedness of the crystal structure. One example is electrical
magnetochiral anisotropy (eMChA), a change in resistivity that depends linearly
on the applied current and magnetic field. A strong eMChA was recently reported
for $p$-doped tellurium. With this motivation, we carry out an \textit{ab
initio} study of its bulk eMChA response as a function of temperature and
doping concentration. We use the semiclassical Boltzmann transport formalism
within the constant relaxation-time approximation to express the current
density at order $E^2B$ in terms of the energy dispersion, intrinsic magnetic
moment, and Berry curvature of conduction electrons. We find that the orbital
Zeeman coupling dominates the response, with smaller contributions coming from
the spin-Zeeman coupling and from the Berry curvature. The agreement with the
available experimental data is satisfactory.
