What is inrush current?..

Answer / Shany Singh

Inrush current is a high transient current that occurs when an electrical device, such as a motor or transformer, is first energized or re-energized. This surge of current can be up to several times the normal operating current and lasts for a short duration (usually a few cycles). It is caused by the device's core and windings becoming magnetized when power is applied.
