Use the High Current Sensor in experiments that involve currents larger than 1 A, such as solar panels, hand generators, and other alternative energy projects. The High Current Sensor has a range of ±10 A. Current is measured with a Hall Effect sensor, which uses the magnetic field created by the current and therefore does not add a resistive element to the circuit. A metal shield over the Hall Effect chip reduces the influence of external magnets. A replaceable fuse protects the equipment and circuit

The Constant Current System is a DC power source with a built-in current probe designed for use in electrochemistry experiments, and as such eliminates the need for a separate power supply when performing electroplating and electrolysis experiments in Chemistry. It is capable of delivering 0.6 A at 5VDC 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.
