What is a potentiostat and how to connect a potentiostat?

In this video we'll be talking about what a potentiostat, galvanostat and a frequency analyzer are, why you would use them, and how to connect the electrodes. You can see examples of classic and screen-printed electrodes and four different types of electrochemical techniques. A potentiostat is a lab instrument that is used for measuring the current while applying a voltage. By understanding how a potentiostat works, you will be able to use it more effectively in your lab experiments. This video is designed to give you a basic understanding of the instrument, how to connect your electrodes and what electrochemical techniques exist.
