Vref:This is the reference output. It provides charging current for capacitor CT through resistor RT.
这是参考输出。它提供了电容CT充电电流通过电阻RT。

In this case, the series resistor should be placed as close to the relay as possible to limit the current when charging the cable capacitance.
在这种情况下，串联电阻就应该尽量靠近继电器，以限制电缆电容充电时的电流。

Several electrochemical determination methods to test the corrosion resistance of coated metals were described, such as DC resistor, AC resistor, potential time and charging curve.
