Does Constant Inductor Current Or Noncurrent Cause Any Inductive Effect Explain Why

An inductor is formed by a cylindrical core with many turns of conducting wire. The input source has been.

However this rarely happens and only in ac circuits containing pure resistances.

Does constant inductor current or noncurrent cause any inductive effect explain why. Check youtube for the promo. Is praposnal to current for same inductor we can say inductor is a current sensitive device. Ask question asked 4 years 5 months ago.

Why do inductors maintain the exact same current. Read about magnetic fields and inductance inductors in our free electronics textbook network sites. An inductor is called as such because its magnetic coupling is high.

Why is the integration constant in a purely inductive ac circuit assumed to be zero. Inductors react against a change in current. So it generates a negative voltage across it.

An inductor is a passive device that stores energy in its magnetic field and returns energy to the circuit whenever required. How does an inductor work. One important point to note about the above equation.

If you start with thinking about current through an inductor what you have to think about is the rate of change of current through the inductor resulting in certain amplitude of voltage across it that opposes the rate of change. Any current in a coil causes a magnetic field. Why current goes to zero as frequency increases.

As the wire resistance in any normal inductor is enough to cause current to decay very quickly with. When an inductor is connected to a circui. When you allow a magnet to fall freely through a hollow metal tube it will not fall with that famous acceleration of 98ms2.

In case of dc current the magnetic field doesnt have any further effects but an ac current will also cause the field to change all the time. A lagging current indicates an inductive circuit. In other words the magnetic field it creates will have an effect on the element itself.

Rather it will be slowed down while it is in the vicinity of the tube. Most ac circuits contain some type of inductance in which case the current waveform lags the voltage or reaches its peak slightly after the voltage waveform. Voltage and current sine waves are in phase when they peak and cross the zero axis at the same time.

Why is its behavior so counter intuitive. Inductors resist a change in current flow just like capacitors resist a change in voltage. Applying a voltage to its terminals will produce a current that will then create a magnetic field like any other wire.

It only relates the emf produced across the inductor to changes in current because if the flow of inductor current is constant and not changing such as in a steady state dc current then the induced emf voltage will be zero because the instantaneous rate of current change is zero didt 0. An inductors ability to store energy as a function of current results in a tendency to try to maintain current at a constant level.
