1、名师推荐精心整理学习必备第十五章第 2 节电流和电路一、电流1、电荷 的定向移动形成电流；（电荷包括正电荷和负电荷定向移动都可以形成电流）3、规定：正电荷定向移动的方向为电流的方向（负电荷 定向移动的方向与电流方向相反，尤其注意 电子是负电荷，电子的移动方向与电流的方向相反）4、在电源外部，电流的方向从电源的正极流向用电器，再回到负极；5、二极管是 半导体，具有单向导电性，即电流只能从它的一端流向另一端，不能反向流动。6 电流的概念：电流等于1s 内通过导体横截面积的电荷量。说明：电流只与电荷量、通电时间有关，与导线的粗细，即横截面积的大小无关。7、物理意义：电流表示 电流的大小或强弱。8、计
2、算电流的公式：I=Q/t 其中 I 表示 电流，单位是：安培 A；Q表示：电荷量，单位是：库仑 C；t 表示 时间，单位是：秒 s 9、单位：1、国际单位：A 2、常用单位：mA、A 3、换算关系：1A=1000mA 1mA=1000A 某同学用台灯工作时电流约140 mA，合 0.14 A 它表示：1s 内通过导体横截面积的电荷量0.14 C。2s 内通过导体某一横截面积电子数为：1.75 1018个。10、测量：1、仪器：电流表，符号：2、方法：读数时应做到“三看清”即看清接线柱上标的量程，看清每大格电流值、看清每小格电流值 使用时规则：电流表要 串联 在电路中；电流从电流表的正接线柱 流
3、入，负接线柱 流出，否则 指针反偏。被测电流不要超过电流表的最大测量值 危害：被测电流超过电流表的最大测量值时，不仅测不出电流值，电流表的指针还会被打弯，甚至表被烧坏。选择量程：实验室用电流表有两个量程，00.6A 和 0 3A。测量时，先选大量程，用开关 试触，若被测电流在0.6A3A 可 测量，若被测电流小于0.6A 则 换用小的量程，若被测电流大于3A则换用更大量程的电流表。绝对不允许 不经用电器直接把电流表连到电源两极上，原因电流表相当于一根导线。名师推荐精心整理学习必备二、电路电路：用导线将用电器、开关、用电器连接起来就组成了电路；1、电源：提供持续电流，把其它形式的能转化成电能；电
4、路2、用电器：消耗电能，把电能转化成其它形式的能（电灯、风扇等）；的构成3、导线：，连接电路的各个元件，输送电能；4、开关：控制电路的通断；三、电路的工作状态1、通路：处处连通的电路；2、开路（断路）：某处断开的电路；3、短路：不经用电器用导线直接将电源的正负极；四、得到持续电流的条件：1、必须有电源，2、电路必须是通路。五、电路图及元件符号：用符号表示电路连接的图叫电路图，常用的符号如下：画电路图时要注意：整个电路图是长方形；导线要横平竖直；元件不能画在拐角处。基础训练一、填空题文档编码:CV8D8R1Z8X2 HH9S1M9H5C10 ZQ9I7B10J1I7文档编码:CV8D8R1Z8X
