This instrument allows students to feel about the electricity by hand touching in the physics lesson.
Working theory: this electricity generator produces 50V ~ 110V by shaking it, you can feel the electricity with your hand touching in the feeling area.
Specifications;
A. Output voltage: velocity of rotate is 1000 ~ 1200 circles / per minute, while the output is higher than 110V
B. Output current: ≥0.5Ma
C. Whole machine’s character: the handle is flexibly, and after shaking it two minutes, the belt will not slip and release, its generate electricity normally.
