Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. Example

[0028] This embodiment provides a physical electrical experiment board for convenient display, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the physical electrical experiment board includes a base 1, a display frame 2 hinged on the base 1 for buckling with the base 1, a display panel 3 fixedly arranged inside the display frame 2, a circuit board 4 fixedly arranged on a side of the display panel 3 close to the inside of the display frame 2, and an experimental device 5 connected to the display board 3 by bolts 6; a connecting line 41 for connecting the experimental device 5 to form an experimental circuit is provided on the circuit board 4, and an electrical schematic diagram 31 corresponding to the experimental circuit is drawn on the display board 3; wherein, a terminal 42 for connecting to the bolt 6 is fixedly provided at the connection node position of the connecting line 41 corresponding to the experimental device 5.

[0029] When in use, open the display frame 2, make the display panel 2 stand on the base 1, and then connect the experimental device 5 to the terminal 42 through the bolt 6 according to the electrical schematic diagram 31 displayed on the display board 3, and connect the experimental device 5 to the connecting line 41 to form an experimental circuit to perform an electrical experiment; wherein, the electrical schematic diagram 31 on the display board 3 can prompt the experimental subject to use the corresponding experimental device 5, which is convenient for the experiment, and the electrical schematic diagram 31 of the experimental circuit can be intuitively seen from the display board 3, which is convenient for teaching.

[0030] Furthermore, the base 1 has grooves 11 respectively adapted to the experimental device 5 and the bolts 6; after the experiment is completed, the experimental device 5 and the bolts 6 are removed from the display board 3 and placed in the corresponding grooves 11 for storage, which facilitates the storage of the experimental device 5 and the bolts 6 and avoids the loss of the devices.

[0031] Furthermore, a lighting lamp 7 is provided on the display board 3 at a position above the experimental device 5; when conducting an experiment, the lighting lamp 7 can be turned on to illuminate the display board 3, so that the electrical schematic diagram 31 on the display board 3 is displayed more clearly, thereby facilitating students to watch and experimenters to install the experimental device 5.

[0032] Furthermore, a handle 21 is fixedly installed on the top of the display frame 2; after the experimental teaching is completed, the display frame 2 can be snapped onto the base 1, and the handle 21 provides a hand-held portion for the physical and electrical experiment board to facilitate extraction.

[0033] Specifically, in order to realize the volt-ampere characteristic curve experiment of the small light bulb, the experimental device 5 includes a battery box 51, a switch 52, an LED lamp bead 53, a sliding rheostat 54, a current detection device 55 and a voltage detection device 56.

Among them, the current detection device 55 is a digital display ammeter, and the voltage detection device 56 is a digital display voltmeter.

[0034] It can be understood that what is drawn on the display board 3 is the electrical schematic diagram 31 of the small light bulb volt-ampere characteristic curve experiment, and what is arranged on the circuit board 4 is a battery box 51, a switch 52, an LED lamp bead 53, a sliding rheostat 54 and a current detection device 55 for the small light bulb volt-ampere characteristic curve experiment in series, and the voltage detection device 56 is connected in parallel at both ends of the LED lamp bead 53, forming a connection line 41 of the small light bulb volt-ampere characteristic curve experimental circuit.
