高二人教版英语上册第二单元知识点：电热与焦
耳定律
“物理”二字出现在中文中，是取“格物致理”四字的简称，即考察事物的形态和变化，总结研究它们的规律的意思。

查字典物理网为大家推荐了高二人教版英语上册第二单元知识点，请大家仔细阅读，希望你喜欢。

电热：
(1)电流的效应：电流通过导体时电能转化成热，这个现象叫做电流的热效应.
(2)电流热效应的实质：是电流通过导体时，由电能转化为内能.
(3)电热器：电流通过导体时将电能全部转化为内能的用电器.其优点是清洁、无污染、热效率高，且便于控制和调节电流.
(4)有时人们利用电热，如电饭锅、电熨斗等;有时人们防止电热产生的危害，如散热孔、散热片、散热风扇等.
焦耳定律：
(1)内容：电流通过导体产生的热量跟电流的二次方成正比，跟导体的电阻成正比，跟通电时间成正比，这个规律叫焦耳定律.
(2)公式：Q=I2Rt，公式中的电流I的单位要用安培(A)，电阻R的单位要用欧姆(Ω)，通过的时间t的单位要用秒(s)。
