Why does the inductor not consume power?

In a strict sense, the inductor does not consume electrical energy. When the inductor is connected to DC, the inductor is charged. After charging, the two levels of charge are theoretically never seen unless you discharge. When the AC power is connected, the inductors are charged and discharged differently, and the power of the grid is not consumed.

However, since the inductor is continuously charged and discharged in the AC circuit, it is theoretically thought that the electric energy has no work for the inductor, and the inductor consumes unnecessary power. You know when you compare the resistance. When a current flows through the resistor, the resistor heats up and the electrical energy is converted into heat, which means that the resistor consumes power.
