Application of Resistance Loads in the Testing of Household and Similar Electrical Appliances

In the safety test process of household and similar electronic appliances, adjustable resistive loads are often required For example, the measurements of low-power circuits, the overload protection test of transformers, the flexing test, some abnormal operation tests, and testing of appliances with reserved power supply for other devices. This article introduces several common resistive loads, specific selection and usage methods are provided to improve the test efficiency using the above test as examples.
