求翻译：为使通过用电器的电流不超过额定值或实际工作需要的规定值，以保证用电器的正常工作，通常可在电路中串联一个可变电阻。当改变这个电阻的大小时，电流的大小也随之改变，我们把这种可以限制电流大小的电阻叫做限流电阻。是什么意思？

Through electrical current does not exceed rated value or practical work needs to be regulation to ensure that the electrical work, usually in the circuit a variable resistor in series. When you change the size of the resistance, so does the size of the current changes, we can limit the current size
