THEORY OF OPERATION

The power booster is an amplifier built to interface directly with
potentiostat/galvanostat instruments. This section describes the way in which the
booster inter-acts with these instruments.
The main function of a potentiostat is to apply a defined voltage to a load and to
measure the resulting current through it. Similarly, a galvanostat maintains a
defined current through a load and measures the resulting voltage across it. To
perform these tasks, the potentiostat/galvanostat plus booster can be connected to
two, three or four-terminal cells. (See Figure 1-3.)
