Final answer:
The resistance of an AC magnetic device will have lower resistance than Ohm's law predicts due to inductive reactance.
Step-by-step explanation:
The resistance of an AC magnetic device will have lower resistance than Ohm's law predicts. The resistance of an AC magnetic device will have lower resistance than Ohm's law predicts due to inductive reactance.
In Ohm's law, the relationship between voltage (V), current (I), and resistance (R) is given by V = IR. However, AC magnetic devices, such as inductors, have a property called inductive reactance, which affects their resistance. Inductive reactance is a type of AC resistance that depends on the frequency of the alternating current and the inductance of the device.
Due to inductive reactance, the resistance of an AC magnetic device will be lower than the resistance predicted by Ohm's law.
