Temperature dependences of the resistivity tensor components rhoab and rhoc were measured for YBa2Cu3O7 - x single crystals with different oxygen contents. The resistivity anisotropy rhoc/rhoab was found to grow exponentially with decreasing temperature. The results are compared with the predictions of different models describing transverse transport in the normal state of cuprate high-Tc superconductors.
