Hand touch battery

FMD8101 Hand Touch BatteryProduct Introduction

This instrument can deflect the pointer of the ammeter by the movement of charges generated when the metal plate is touched by hand, indicating the generation of current in the circuit.

Experimental phenomenon: When the bidirectional switch is thrown on one side and both hands are pressed on the copper and aluminum plates in the shape of hands, it can be observed that the microampere meter pointer is biased towards one side; Then throw the bidirectional switch to the other side and repeat the above action, and you can observe that the microampere meter pointer is biased towards the other side; If you stick some water on your hands before demonstrating, you can see that the meter reading increases significantly; When different experimenters operate, the indication of the electricity meter also varies greatly, which can inspire students to think.

Dimensions: 360 × 360 × 320mm;
