Electrical properties include the study of the Hall effect as well as the electrical conductivity of a combination of PVA compound solution with multiple nanotubes. Hall coefficient, electrical conductivity and some other constants, as well as the type of charge carriers were measured. These samples were attended by different concentrations of the various carbon nanotubes added to PVA (0.0025, 0.0050 and 0.0075 g). The values ​​of electrical conductivity are increased and the Hall coefficient of pure and graded polymer films decreases with increasing rates of vaccination with multiple carbon nanotubes. The results showed low resistance values ​​with all concentrations of multiple nanotubes of carbon nanotubes. The values ​​of mobility decreased with increased concentrations after vaccination. The results also showed that the activation energy decreases with the increase in vaccination rate.
