How It Is Used
One or two rods are dipped into an electrolyte in a beaker or voltameter and connected to a DC supply through the brass terminals. Because carbon does not react with most electrolytes, the rods carry current without dissolving, for experiments on electrolysis, Faraday’s laws and building simple cells.
