dielectric breakdown voltage การใช้

The positive feedback increases the accumulating charges exponentially until the dielectric breakdown voltage of the air is reached and an electric spark jumps across the gap.
The laser energy reduces the atmospheric dielectric breakdown voltage and the air is made less insulating by superheating, which lowers the density ( p ) of the filament of air.
The substrates are characterized by several key parameters, chiefly thermomechanical ( glass transition temperature, tensile strength, shear strength, thermal expansion ), electrical ( dielectric constant, loss tangent, dielectric breakdown voltage, leakage current, tracking resistance . . . ), and others ( e . g . moisture absorption ).
