These circuit modules are designed specifically for introductory circuits investigations. 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.

Each module connects mechanically to another by sliding the tabs into each other. It works on any tabletop. No special surface is required. To electrically connect two modules, students insert a jumper clip, which emphasizes that an electrical connection has been made. 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.

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. Since the Current Sensor Module is in the same form factor as the other modules, it naturally fits in series with the circuit components. 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. There are no extra wires to confuse students.

Two different Modular Circuits Kits are available.

The Basic Modular Circuits Kit is a lower cost, introductory set with fewer components than the Essential Physics Modular Circuits Kit. The Wireless Voltage Sensor and Wireless Current Module are not included. The Basic Kit has enough modules to do five of the experiments listed below.

This product, the Essential Physics Modular Circuits Kit, includes more modules, such as the Wireless Current Sensor Module and Wireless Voltage Sensor, and can perform all 11 of the experiments listed below. The Essential Physics Modular Circuits Kit will also support applications like RC and RLC circuit analysis, electric motors, Kirchhoff’s Laws, and much more!
