Actually, I am trying to build a current monitor for a wireless sensor network. I am going to use a current sense resistor as the current will pass through the resistor. By measuring the value of the voltage, the current value can be calculated.
My application is very sensitive as the current that will be measured is in the range of mA, 30 mA maximum.
When it came to buying the resistors I got confused. I found a type of resistor called 'precision resistor' that has a very small error, and another one called 'current sense resistor'. I wasn’t sure what were the differences between these to types of resistors, not until one day I reached out to Thunder-precision resistor, their customer service department presented a clear explanation to me.
电阻元件的电阻值大小一般与温度，材料，长度，还有横截面积有关，衡量电阻受温度影响大小的物理量是温度系数，其定义为温度每升高1℃时电阻值发生变化的百分数。电阻的主要物理特征是变电能为热能，也可说它是一个耗能元件，电流经过它就产生内能。电阻在电路中通常起分压、分流的作用。对信号来说，交流与直流信号都可以通过电阻。
Precision resistors is of low tolerance and low temperature coefficient, Thunder Precision Resistors makes ultra precision resistors and ultra precision resistor networks.
