A Teaching Aid for Ohm's Law

Abstract

The invention relates to an Ohm's law teaching aid, which includes: an ohm circuit module connected to a first power supply and a detection module, the ohm circuit module is used to connect circuits according to Ohm's law, and the detection module is used to detect the current signal and voltage signal of the ohm circuit module, the first A power supply is used to provide stable power for the ohmic circuit module; the display module is connected to the detection module; one end of the water flow simulation module is connected to the second power supply, and the other end of the water flow simulation module is connected to the ohmic circuit module. The Ohm's law teaching aid of the present invention uses a contrasting method to represent the abstract current, voltage and resistance as the flow velocity of the water flow, the height of the water outlet and the shielding area of ​​the baffle, and through the mutual matching circuit connection and device structure connection, Realize the synchronous change of the circuit state and the water flow state, so that the teaching efficiency of teachers and the learning efficiency of students can be greatly improved.

Description

technical field [0001] The invention relates to the field of electrical teaching, in particular to a teaching aid for Ohm's law. Background technique [0002] In the existing teaching process of physics and electrical knowledge in primary and secondary schools, most teachers have difficulty in teaching abstract concepts such as current and voltage to students smoothly, and students with poor understanding of abstract concepts will find it difficult to accept. And affect the subsequent learning process. [0003] Although in the teaching process, each teacher will adopt a variety of new teaching methods, it is difficult to find a concrete way to express abstract concepts, which seriously reduces the teaching efficiency of teachers and the learning efficiency of students. [0004] Especially in the teaching process of Ohm's Law, it is difficult for students who have just come into contact with abstract concepts such as current and voltage to understand the relationship between...

[0002] In the existing teaching process of physics and electrical knowledge in primary and secondary schools, most teachers have difficulty in teaching abstract concepts such as current and voltage to students smoothly, and students with poor understanding of abstract concepts will find it difficult to accept. and affect the subsequent learning process

[0003] Although in the teaching process, each teacher will adopt a variety of new teaching methods, it is difficult to find a concrete way to express abstract concepts, which seriously reduces the teaching efficiency of teachers and the learning efficiency of students

[0004] Especially in the teaching process of Ohm's Law, it is difficult for students who have just come into contact with abstract concepts such as current and voltage to understand the relationship between current, voltage and resistance. The existing teaching aids for Ohm's Law can only verify the formula of Ohm's Law, and cannot directly reflect the resistance , voltage, and current, and it is cumbersome to repeatedly disassemble and assemble the line
