环顾我们周围的用电器,电冰箱、洗衣机、节能灯、电饭锅、手机、电子表……在其铭牌或说明书上,都必不可少“电功率”这一参数,并且各种不同用电器的电功率各不相同.电功率是同学们在学习了欧姆定律及电能的基础上所学习的一个重要的电学概念.电功率是描述电流做功快慢的物理量电流通过各种不同的用电器,可以将电能转化为其他形式的能.例如,电流通过洗衣机将电能转化为 Looking around our use of electrical appliances, refrigerators, washing machines, energy-saving lamps, rice cookers, cell phones, electronic watches ... ... in its nameplate or manual, are essential “electric power ” this parameter, and a variety of different Electrical power varies from one electrical power to another electrical power is an important electrical concept that students learn on the basis of Ohm’s law and electrical energy.Electric power is a physical current that describes how fast and slow the electrical current flows through a variety of electrical consumers that can transfer electrical energy For example, the electric current is passed through the washing machine to convert the electric energy into
