Khi 2 vật tiếp xúc chặt chẽ với nhau thì chúng có khả năng truyền 1 số eletron. Khi được cọ xát, số lượng các điểm tiếp xúc chặt chẽ với nhau tăng lên rất lớn, chính vì thế, số e di chuyển từ vật này sang vật kia cũng tăng đáng kể. Lúc đó, 1 vật thừa e và 1 vật thiếu e, dẫn đến hiện tượng tích điện. Vật thừa e tích điện âm, thiếu e tích điện dương. Đó là bản chất của nhiễm điện do cọ xát.
Trên đây cũng chính là 1 phần của thuyết electron: Do khối lượng của e rất nhỏ nên tính linh động của chúng rất lớn. Vì thế, ở 1 điều kiện nào đó như cọ xát, nung nóng, e có thể bứt ra khỏi nguyên tử này để chuyển sang nguyên tử khác, làm cho các vật nhiễm điện.
