Basics of Inductors
In most common terms, Inductors are electrical devices used in a number of applications, specifically in radio frequency circuits. Inductors are directly related to capacitors and could in some ways be considered their opposite. In a capacitor, the amount of energy is calculated by the capacitance and the voltage, as in an inductor, the equation is the same, other than the inductance replaces capacitance.
Inductors are tagged by their rate of inductance that is given in the average unit of Henrys (H). An easy discussion definition of Henrys could be found by taking an inductor of 1 Henry and operating 1 volt across it that would in turn result in a current rising by 1 amp/s. We could present this in an equation of V = L (di/dt), where V is the voltage, L is a size of henrys, di is altered in current, and DT is a rate of time.
Inductors are usually used in radio frequency tools to quiet meddling and stop it from being transmitted. They are used in making transformers, too. A transformer is, basically, just two or more inductors placed together so that their magnetic fields overlap.
The most fundamental inductors are just firmly wrapped coils of wire. Usually, inductors are wrapped in the region of some sort of core material in order to raise the inductance of the existing wire. Iron is far and away the most usual core material used for inductors, though ferrite is as well extensively used.
Any conductor would have some value of inductance, just because there is a current to be opposed. Inductors are chiefly designed to make this inductance, nevertheless. When we speak of inductance, we are actually speaking about a magnetic field, which is made by altering the current that runs by way of a medium. By wrapping a wire into a coil about itself, the value of current required to make a magnetic field of a given power is condensed accordingly, and the more times the wire is covered, the less current is required. By using a core material like iron, rather than allowing the coil enclose air; the magnetic field made by the inductor is detained in to the inductor body, increasing the overall inductance.

I need some help with integrating Electromagnetic induction?
So we have an magnet we going to let it drop from different heights through an inductor. What will you notice of the maximum value of the integral of these different heights?
The equation of the electromagnetic induction is: Uind= = N ?(??)/(?t)?
If i integrate this I will get ? Uind(t)= N??ln(t) but that suggests that with lower heights you would get a greater maximum value of integral, because with greater heights the speed is lower so he will go longer through the inductor and thus t will be greater, but this can't be right, right? :p
Please explain (A)

An LC circuit consists of a capacitor, C = 3.16 ?F, and an inductor, L = 5.80 mH. The capacitor is fully charg?
An LC circuit consists of a capacitor, C = 3.16 ?F, and an inductor, L = 5.80 mH. The capacitor is fully charged using a battery and then connected to the inductor. An oscilloscope is used to measure the frequency of the oscillations in the circuit. Next, the circuit is opened, and a resistor, R, is inserted in series with the inductor and the capacitor. The capacitor is again fully charged using the same battery and then connected to the circuit. The angular frequency of the damped oscillations in the RLC circuit is found to be 16.0% less than the angular frequency of the oscillations in the LC circuit.
a) Determine the resistance of the resistor.
b) How long after the capacitor is reconnected in the circuit will the amplitude of the damped current through the circuit be 53.5% of the initial amplitude?
c) How many complete damped oscillations will have occurred in that time?

Help designing an active filter circuit?
I need to design an active filter (no inductors) that has the following characteristics:
https://www.u-cursos.cl/usuario/f036a4af1eb1f207e07584e136fb7e9f/mi_blog/r/Screenshot_at_2012-04-25_15:42:49.png
As you see is a bandpass filter. It has to be a Butterworth filter, however I know nothing about that, any guide or suggestion on how to start???
