Figure 4: Plot of normalized current “ ๐œ“ ” versus the reaction/diffusion parameter “ ๐›พ ” at a microelectrode modified using a conducting polymer film. (a) (i) ๐›ผ = 0 . 1 , 1 , the current was calculated using (6) and (11) for all small and medium values of ๐›ผ . (b) (i) ๐›ผ = 5 , (ii) ๐›ผ = 1 0 , (iii) ๐›ผ = 1 0 0 , the current was calculated using (9) for all large values of “ ๐›ผ ”. (c) (i) ๐›ผ = 0 . 0 1 , 0 . 1 , 1 (ii) ๐›ผ = 1 0 , (iii) ๐›ผ = 5 0 , and, (iv) ๐›ผ = 1 0 0 , the current was calculated using (9) and (11) (solid line) (11); (dotted line) (6). Solid lines are compared with points.
