The reasons for the spark when the power cord of the Xiaomi Multifunctional IH Rice Cooker is plugged in are listed below:
1. A spark when plugging in the power cord of a rice cooker is caused by a brief electrical discharge when the power supply is initially connected. When you first plug in the rice cooker, it can draw a brief surge of current to charge capacitors or power internal components like the heating element. This surge, known as an "inrush current," can cause a small spark;
2. In the normal conditions, electrical equipment will generate surge current when it is powered on, and there will be a slight spark between the socket and the plug to a certain extent;
3. In addition, if the conductive copper sheet of the socket is deformed or loose, sparks will be more obvious. It is also recommended to use a good quality socket, preferably with a switch.
