GI series :5000w dc to ac off grid inverter
Macroscopically, objects with electric charge are called "charged objects". If two objects have a positive charge or both have a negative charge, the two objects are called "same electric", otherwise they are called "heteroelectric". Like-electricity repels, opposite-electricity attracts. To do a simple experiment, first rub the felt cloth on the glass rod to charge the glass rod (with electric charge), and then touch the glass rod with two light balls A and B suspended in midair by ropes. At this time, it can be observed that , the two light spheres A and B will repel each other because they both have the same electric charge. Rub another piece of felt cloth against the amber stick to charge the amber stick, and then touch the amber stick to the other two light balls C and D suspended in midair by ropes. At this time, it can be observed that the light balls C and D are also will repel each other because they also have the same electric charge. However, the light spheres A and C attract each other because they have different electric charges. If a charged object absorbs the same amount of heteroelectric charge, the object becomes electrically neutral and will not be attracted or repelled by any charged object.
