what is an inductor used for
A transistor acts like a resistor when Gate is connected to Source.
Since we know that inductance of an inductor depends on the length of inductor by the formula L=muAN*N/l, where l is the length of inductor. So by varying the length of inductor we say that inductance of inductor varies.
Water molecules are uncharged and polar.
The charged body will induce a separation of charges in the uncharged body.The charged body will induce a separation of charges in the uncharged body.The charged body will induce a separation of charges in the uncharged body.The charged body will induce a separation of charges in the uncharged body.
gama radiation is uncharged. Alpha is positive and beta is negative.
If an electrically uncharged body is contacted by an electrically charge body then the uncharged body will gain a charge. This is because electricity flows from a higher concentration to a lower concentration and will balance out.
In an ideal inductor, no, there is no voltage induced across an inductor unless the current in the inductor is changing. However, since there are no ideal inductors nor power supplies, eventually an inductor will draw a constant current, i.e. the limit of the power supply; and, since no inductor has zero ohms at equilibrium, that current will translate to voltage.
This is called a molecule, though it doesn't exactly react as if it were a single atom in chemical changes.
any conductor wound with few turns can be considered as an inductor
No, after it becomes uncharged there with be "(broken)" at the end of the name and you will no longer be able to wield it.
Some of them are: 1. Inductor temporarily stores energy in form of magnetic field. It is given by E=½LI² here L is inductance & I is current. 2. Inductor causes current to lag voltage by 90°. 3. Inductor consumes reactive power. 4. Inductor oppose current change in circuit for AC only. Fo DC it act as simple wire. 5. Inductors are used for blocking the AC while passing the DC. They are known as chokes. 6. Inductors are used to create magnetic fields in electrical machines for the purpose of energy conversion.
