物理学中讲:物体能够吸引轻小物体,就说它带了电或有了电荷.这种说法阐明了“电荷”与最初所讲的“电”的关系.这里所说的“电”指的是最具普遍意义的电,而“电荷”是一种电的量度或者说是一种表现形式.人们常说的“电”是一种宏观概念,“电荷”顾名思义就是一种微观粒子的负荷. Physics says that an object can attract a light object, say it has a charge or a charge, and that it states the relationship between “charge ” and the original “power”. “Electric ” refers to the most common sense of electricity, and “charge ” is a measure of electricity or a form of expression.People often say “electric ” is a macro concept, “Charge ” as the name suggests is a load of microscopic particles.
