Description
Technical field
The utility model relate to a kind of Ohm law entity apparatus for demonstrating for imparting knowledge to students.
Background technology
Usually on classroom, the lecture experiment of Ohm law is all demonstrated by screen, books, traditional teaching demonstration method is too abstract for student, visual poor, be unfavorable for the understanding of student to the relevant knowledge such as principle, scale feature, current direction, reading area of ohmmeter, and in the retrofit process of whole experimental provision, student is just as the angle views of observer, do not participate in person in the operating process of experiment, be unfavorable for the impression of deepening student.
Utility model content
For the deficiencies in the prior art, the utility model provides a kind of Ohm law entity apparatus for demonstrating for imparting knowledge to students, and its structure is simple, and teaching efficiency is better.
For achieving the above object, the utility model provides a kind of Ohm law entity apparatus for demonstrating for imparting knowledge to students, include reometer, switch, electric battery and variable rheostat, described reometer, switch, electric battery and variable rheostat are connected into a loop, and described variable rheostat is provided with the knob for regulating resistance size, also include a demonstration board, the corresponding reometer groove be provided with for setting-in fixed current table on described demonstration board, for the switch fixed switch recess of setting-in, for the electric battery groove of setting-in self-contained battery group, the variable rheostat groove of variable rheostat is fixed for setting-in, described demonstration board is also removably fixed with a clipboard, described clipboard is provided with the camber line coaxial with original scale on reometer, described clipboard is movably set with a contact pin, for being connected with a fine rule between the bolt of fixing tuning drive gear and this contact pin on reometer.
The beneficial effects of the utility model are: by the setting of demonstration board and respective slot, entity (reometer, switch, electric battery and variable rheostat) for demonstrating Ohm law can be fixed on demonstration board, thus student can be demonstrated by entity intuitively deepen to understand Ohm law relevant knowledge.In specific experiment process, student is first by the knob on turn variable rheostat, change resistance value, accordingly reometer will produce correspondingly current indication, after this stretching fine rule the tuning drive gear on this fine rule and reometer is kept on the same line, accordingly contact pin is fixedly inserted on clipboard, then along fine rule, it clipboard is the extended line of pointer in reference graduation line drawing with camber line, correspondingly resistance value on mark simultaneously, such resistance value and with this resistance value accordingly current value can show intuitively, according to Ohm law U=IR, correspondingly can draw the reading of corresponding voltage, thus the relevant knowledge of Ohm law can be obtained by the demonstration of this entity, and then effectively intensification student understands Ohm law relevant knowledge, greatly promote teaching efficiency.
As further improvement of the utility model, be adhesively fixed by velcro between described clipboard and demonstration board.
As further improvement of the utility model, between described clipboard and demonstration board by magnet and iron block attracting fixing.
Demountable structure between above-mentioned clipboard and demonstration board, is convenient to change the clipboard marked, facilitates the experimental implementation of next bit student.And the clipboard changed also can as the marking foundation of experimental implementation.
As further improvement of the utility model, described demonstration board is also connected with a base, and described base comprises oblique frame and transverse slat, and the back of demonstration board is fixed in one end of described oblique frame, the other end of described oblique frame is connected with transverse slat, and described demonstration board is supported on transverse slat.Described base can prevent falling of demonstration board, better Protection equipment, reduces unnecessary loss.
