| Abstract | ||
| This study includes investigates the electrical behavior of high density polyethylene (HDPE) having various concentrations of carbon black (C.B.) over a range of frequencies from (100Hz) to (20KHz).Experimental results display that the dielectric constant and a.c. conductivity increase with increasing C.B. concentrations in the samples which have the same thickness but different concentrations, especially in sample (90%HDPE+10%C.B.). The dielectric constant and a.c. conductivity increase with increasing of thickness of samples which have the same concentration of C.B. because the effect of the dipole moment on the sample has large thickness. | ||
