The fact that the Current Sensor is wireless helps the pedagogy: There is only one way in and one way out of the Current Sensor. Since the Current Sensor Module is in the same form factor as the other modules, it naturally fits in series with the circuit components. Students will learn the correct way to insert an ammeter into a circuit: First they remove one of the straight wire modules from their circuit and then they replace it with the Wireless Current Sensor Module. The large size of the modules (8 cm x 8 cm) enables all the students around the table to see and understand the completed circuit. To electrically connect two modules, students insert a jumper clip, which emphasizes that an electrical connection has been made. For students who have never wired a circuit, this modular system makes it easy for them to see their circuit physically laid-out exactly as it appears in their circuit diagram.Įach module connects mechanically to another by sliding the tabs into each other. These circuit modules are designed specifically for introductory circuits investigations.
