The Constant Current System is a DC power source with a built-in current probe designed for use in electrochemistry experiments.

Description

The Constant Current System eliminates the need for a separate power supply when performing electroplating and electrolysis experiments in chemistry. It is capable of delivering up to 0.6 A at 5 V DC.

A current-sensing resistor allows monitoring of the output current through the sensor cable. The user can set the current by tuning the dial with the system automatically adjusting the voltage.

Use the Constant Current System to explore Faraday’s law and determine Avogadro’s Number.

Note that it can only be used in conjunction with its own built-in power supply—it cannot be used to measure the current of a circuit using a different power supply.
