The electric shock demonstration device comprises a plank, small bulbs, a transformer, metal rods and a metal plate, the metal plate is placed on the plank, the end, installed on the plank, of the transformer is connected with the commercial power, a live line and a null line are led out from the other end of the transformer, the metal rods are installed on the left lower portion of the plank, the metal rods are connected through steel wires, the small bulbs are installed on the steel wires, and the live line and the null line are connected with the steel wires; the electric shock demonstration device further comprises a person-shaped toy and a tree, an iron wire is arranged at the head of the person-shaped toy, metal hooks are arranged on the left hand and the right hand, copper plates are arranged at the foot soles, LED lamp strips are arranged between the left hand and the metal hooks and between the right hand and the metal hooks, LED lamp strips are arranged between the left-hand metal hooks and the left-foot copper plate, a neon pipe is arranged on the abdomen, pipe pins of the neon pipe penetrate through the thighs to be connected with the foot-sole copper plates, and the tree is installed at the left upper corner of the plank. The electric shock demonstration device is safe and easy to operate and visual in simulation.

Description

technical field [0001] The invention relates to the field of teaching aids, in particular to an electric shock demonstrator. Background technique [0002] The part about electric shock in junior high school physics textbooks only talks about two types of electric shock: fire-zero and fire-ground, which is not comprehensive enough, and teachers can’t use commercial electricity to demonstrate to students, which is not conducive to students’ understanding of electric shock. Contents of the invention [0003] In order to make up for the deficiencies of the prior art, the purpose of the present invention is to provide an electric shock demonstrator to make the existing technical solutions more perfect. [0004] An electric shock demonstrator, including a wooden board, a small light bulb, a transformer, a metal rod, and a metal plate. The metal plate is placed on the wooden board, and the transformer is installed on the wooden board. The metal rods are installed on the lower le...
