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

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: 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.

The Environment

Recycling Symbol At IDS Education we are committed to minimising our impact on the environment and helping to create an ecologically sustainable future. We recycle everything we can, from our packaging materials down to our tea bags. As well as this, we carefully select our business partners to ensure they follow a similar code and our major partners are increasingly using solar energy as their predominant source of electricity.
