英语翻译These resistors are insulated and can easily be mounted 英语翻译 These resistors are insulated and can easily be mounted in compact constructions.They are specially constructed for high pulse loads compared to the average load.The nominal load can be improved by forced air cooling or by mounting the resistors on a heat sink. swers1231年前3: 飞浪44 共回答了18个问题 | 采纳率94.4%

这些电阻是绝缘的,并且便于紧凑安放.与普通负载相比,这些电阻经过特殊设计,用来承载高频负载.通过强制风冷或在这些电阻上安装散热片,其额定负载得以提高.

谁能告诉我如何计算这道电路题Special shunt resistors designed to drop 50mV 谁能告诉我如何计算这道电路题 Special shunt resistors designed to drop 50mV in high current-measuring applications are available from manufacturers. A 50mV, 10K ohm full-scale voltmeter is connected across the shunt to make the measurement. 1.What value of shunt resistance is required to use a 50mV meter in a 50A measurement application? 2. How much current is through the meter? 谁能告诉我运算过程,谢谢. LangLaiLa1年前3: shuaizy 共回答了17个问题 | 采纳率88.2%

1.value of shunt resistance is：50mV Dive 50A,the result is 0.001
2.current through the meter is:50A*(0.001*10000/(0.001*10000)),the result is 0.0009999999 ,about to 1mA

There are three 470ohm resistors are connected in series wit There are three 470ohm resistors are connected in series with a 48V source.What is the minimum power rating of the resistors?正确答案是0.543W,谁能解释一下为何3个同样的电阻还有最小值可言?如何计算出这个结果的, 古瑟儿1年前3: wy417317617 共回答了15个问题 | 采纳率100%

晕,你对电阻的参数有一个误解.
电阻的参数除了阻值外,还有一个参数,表征它能够通过的最大电流.通常是用功率表示的,中文叫做额定功率,英文叫做power rating.
这道题是问你这三个电阻的额定功率最小可以是多少（再小就会被烧掉）.
I=48/(3*470)
P=IIR,这个就是每个电阻的实际耗散功率,power rating必须大于这个功率,否则电阻就会烧.

关于贴片电阻的问题,Thin film chip resistors 和 thick film chip resisto 关于贴片电阻的问题,Thin film chip resistors 和 thick film chip resistors 有什么差别 不要直接翻译,我知道,我想了解具体有什么差异,优缺点；前者是Vishay的,后者是YAGEO的 niuniuhewo21年前1: 女人_三十二共回答了15个问题 | 采纳率86.7%

普通厚膜晶片电阻和薄膜晶片电阻在制程上分别使用了厚膜制程和薄膜制程,厚膜制程生产出来的电阻温度系数相对较大,一般是100PPM以上,特殊制造也可以生产50PPM的,误差相对较大,一般是1%或者是5%,特殊可制造0.1%精度,但是较少情况使用,不过普通厚膜制程的功率相对要大一些,如果标准2512功率是1W,特殊生产可以制造2W；薄膜制程生产出来的电阻温度系数相对较低,可以从2PPM开始,一直到普通50PPM全部可以按要求生产,精度生产出来也相对较高,可以生产0.01%到1%之间的任何精度,甚至可以制造更高的精度,但是功率偏低,没有普通厚膜的功率哪么大.以上为目前两种电阻的本质区别.

如图显示电路回路中使用相同的电池、电流表、电阻器.
电池和电流表的阻值可以忽略不计,当一节电池、一块电流表和一个电阻串联时,电流表读数是0.1A.
问：图中流过A1电流表的读数是多少?
