【判断题】
负载流过电流时，将电能转换成其他形式的能（如磁、热、机械能等），叫做电流做功，简称电功
【判断题】
电功的大小与通过负载的电流及加在负载两端的电压和通电时间成正比
【判断题】
电功率，单位是瓦特，简称瓦，用字母W表示
【判断题】
电流表和电压表是最常用的电工仪表，分别用来测量电流和电压
【判断题】
采用磁电式仪表测量直流时，因其测量机构所允许通过的电流很小，不能直接测量较大的电流
【判断题】
电流互感器作为一种辅助测量元件，在电磁测量及继电保护领域内有着极广泛的应用
【判断题】
万用电表是一种多用途、多量程便携式直读仪表
【判断题】
一般万用表可以用来测量直流电流、直流电压、交流电压、电阻等
【判断题】
一般万用表的测量线路由多量程直流电流表、多量程直流电压表、多量程整流式交流电压表以及多量程欧姆表等几种线路组成
【判断题】
万用表的各种测量对象和量程选择，都是靠转换开关来实现的
【判断题】
万用表虽然具有多用途、多量程的优点，但如果使用不当，选择或接线错误，就可能带来烧表或触电的危险
【判断题】
万用表测量中需要切换转换开关时，应当先切断电源。不应在带电的情况下；特别是在高电压、大电流的情况下切换转换开关
【判断题】
万用表的刻度盘上有许多条标度尺，分别用于不同的测量对象
【判断题】
电阻的标度尺大多在标度盘的最上一行，用符号“Ω”标示，读数在线上方
【判断题】
使用万用表测量时，应注意人身和仪表设备的安全。测量时，手部不得触及表笔的金属部分，以免影响测量的准确性和发生触电危险
【判断题】
物体能吸引铁类物质的性质叫磁性。具有磁性的铁磁物质称为磁体
【判断题】
任何磁体都具有两个磁极，当它静止不动时，总是一个磁极指南，另一个磁极指北
【判断题】
磁极是磁体中磁性最强的地方。如果把两块磁体靠近，就会发现磁极间具有异性相斥、同性相吸的特性
【判断题】
磁体周围存在着一种特殊物质叫磁场。磁场具有力和能的特性
【判断题】
磁极间的相互作用力就是通过磁场来传递的
【判断题】
磁力线是互不相交的闭合曲线，在磁体内部由N极指向S极，在磁体外部由S极指向N极
【判断题】
磁力线上任意一点的切线方向，就是该点磁场方向（即放入磁场中该点的小磁针N极的指向）
【判断题】
磁通的单位为麦克斯韦，用字母φ表示，简称麦(Mx)
【判断题】
为了表示磁场的强弱，把垂直于磁场方向的单位面积上的磁通称为磁通密度或磁感应强度，用字母B表示
【判断题】
磁通密度是一个矢量，只有大小，没有方向，可用于描述磁场中各点的性质
【判断题】
如果磁场中各点的磁通密度大小相等、方向相同，则该磁场为匀强磁场
【判断题】
实验证明，通电导体的周围与磁体的周围一样，存在着磁场，这种现象称为电流的磁效应
【判断题】
用右手握住直导线，使拇指指向与电流方向一致，则四指所指的方向就是磁力线方向，即磁场方向
【判断题】
通电导线在磁场中受到力的作用，叫电磁力
【判断题】
改变通电线圈中电流的方向或者改变磁场的方向，线圈转动的方向也会改变
【判断题】
用直流电源供给电流的电动机，叫做直流电动机
【判断题】
换向器的作用在于它能自动改变线圈中电流的方向
