[0023] To protect the box 100 when not in use, a lid 300 is provided to cover it. The lid 300 is connected to the box 100 via a snap-fit ​​connection, thus covering and protecting the box 100. The box 100 is made of PVC plastic, making it small, lightweight, and easy to carry, meeting the needs of various scenarios such as outdoor teaching and on-site demonstrations. Furthermore, the lid 300 is made of transparent acrylic material. This transparency allows users to clearly observe the circuit structure and current flow, facilitating a better understanding of Kirchhoff's laws and improving teaching effectiveness.

[0024] The experimental board 200 is provided with a first resistor socket group 201, a second resistor socket group 202, a third resistor socket group 203, a fourth resistor socket group 204, a fifth resistor socket group 205, a first switch socket group 210, a second switch socket group 220, a third switch socket group 230, a first external power supply socket group 211, and a second external power supply socket group 212.

[0025] The first resistor jack group 201 is used to insert a first pluggable resistor 221, and the second resistor jack group 202 is used to insert a second pluggable resistor 222. The third resistor jack group 203 is used to insert a third pluggable resistor 223, the fourth resistor jack group 204 is used to insert a fourth pluggable resistor 224, and the fifth resistor jack group 205 is used to insert a fifth pluggable resistor 225.

The other end of the fifth resistor socket group 205 is connected to one end of the first external power socket group 211, and the other end of the first external power socket group 211 is connected to the other end of the first switch socket group 210.

When experiments requiring different resistance values ​​are needed, different values ​​of the first pluggable resistor 221, the second pluggable resistor 222, the third pluggable resistor 223, the fourth pluggable resistor 224, and the fifth pluggable resistor 225 can be selected.

[0030] Then, the first pluggable resistor 221 is inserted into the first resistor jack group 201, and the second pluggable resistor 222 is inserted into the second resistor jack group 202. The third pluggable resistor 223 is inserted into the third resistor jack group 203, the fourth pluggable resistor 224 is inserted into the fourth resistor jack group 204, and the fifth pluggable resistor 225 is inserted into the fifth resistor jack group 205.

[0031] By inserting the first pluggable switch 231 into the first switch socket group 210, the branch containing the first switch socket group 210 can be controlled to be closed or opened. Of course, the first switch socket group 210 can also be used to connect an ammeter in series to detect the current in that branch.

[0032] By inserting the second pluggable switch 232 into the second switch socket group 220, the branch containing the second switch socket group 220 can be controlled to close or open. Alternatively, the second switch socket group 220 can also be used to connect an ammeter in series to detect the current in that branch.

[0033] By inserting the third pluggable switch 233 into the third switch socket group 230, the branch containing the third switch socket group 230 can be controlled to close or open. Alternatively, the third switch socket group 230 can be connected in series with an ammeter to detect the current in that branch.

[0034] Of course, a jack array can also be used to connect a voltmeter, which facilitates voltage measurement.

Furthermore, ammeters and voltmeters can be flexibly connected through the corresponding socket groups. This enhances the flexibility of the entire Kirchhoff's law verification experiment. Overall, the plug-in design simplifies and speeds up circuit switching and current measurement, eliminating the need for complex operations, significantly saving experimental time, and improving experimental efficiency.

[0038] To increase the diversity of external power connections, in some further specific embodiments, the Kirchhoff's Law Experiment Box also includes a first threaded connector 251, one end of which is connected to one end of the first external power socket group 211, and the other end of which is connected to the other end of the first external power socket group 211.
