In work offered results of the experimental study space-timing characteristic charge clusters, acquired by the method of diffusing a light in low-conductivity liquids. As a result of conducted experiments was determined that in the vicinity of the electrode exist two connecting processes distinguishing on a distinctive time and coordinate. Quick process (~ 100 μs) running on distances before 50–100 μm is stipulated by forming thick (mainly ion) part of layer in vicinity of electrode. Slow process (~ 5–10 mines) running on distances ~ 200–300 μm is stipulated by forming friable (cluster) part.
