Answer :
- The voltages are not added in a scalar form, but in a vector form, as shown in the phasor diagrams throughout the chapter.
- Kirchhoff's loop rule is true at any instant, but the voltages across different circuit elements are not simultaneously at their maximum values.
- Do not forget that an inductor can induce an emf in itself and that the voltage across it is 90° ahead of the current in the circuit in phase.
What is Inductor?
- Similar to conductors and resistors, inductors are basic parts that serve specialized purposes in electrical devices.
- Inductors are typically coil-like objects encountered in electrical circuits.
- An insulated wire is coiled around the center core to form the coil.
- By briefly holding energy in an electromagnetic field and then releasing it back into the circuit, inductors are mostly used to reduce or regulate electric spikes.
- The majority of power electronic circuits include inductors, which are passive parts that store energy in the form of magnetic energy when electricity is supplied to them.
However, A significant characteristic of an inductor is that it resists changes in the amount of current that passes through it.
