Current Controller Uses Adjustable Exponent

In connection with electrochemical studies (variable-current chronopotentiometry), an instrument was required that would control the current i through a cell as a power of time

i (t) = k tm

in which the exponent, m, can assume a wide range of values of either sign and ranging from perhaps 1/4 to 3.0. Read full article
