FAQ

I have a 9 Volt DC source in series with an inductor, and a switch. Once i close the switch, there is a spike on the screen of my oscilloscope but it is not precisely when I close the switch, a very breif moment later. The spike rapidly comes down to a steady line across the screen - indicating the dc source. Once I open the switch I get the reverse situation, the spike is in the negative and increases to the steady state.I am not truly understanding what is going on here. I connected my leads across the coil, negative to the side of the coil connected from the negative battery terminal, the positive to the other end. I am seeing the voltage drop across the coil, as the current increases is this voltage drop increasing to a maximum point then it suddenly returns to a minimum value where the voltage is source? I am soo confused .Help !!: I suppose coil is inducter you meanthen change of its inductive reactance will determine its change in voltage.since you are having dc source voltage will not change to maximum value when current change to max reason rate of change of current is 0 then. why did you ask 3 times hhhaaahh?s

I plan on making a 500mH inductor, but I'm not sure how big it needs to be to allow the space for the number of turns it needs with a reasonable size wire. (Reasonable size meaning it is readily available and not so small soldering burns through the wire.): TOROID CORE HAS DIFFERENT SIZE AND DIFFERENT FERRITE COMBINATION THAT AFFECT THE TURNS RATIO TO INDUCTANCE. THE BEST WAY TO DO IT BY MEASURE THE FINISHED CHOKE WITH AN INDUCTANT METER, AND THEN EITHER ADD OR REDUCE THE TURNS. WIRE SIZE IS THE KEY FACTOR TO DETERMENT ITS CURRENT RATE. 500MH WOULD NOT BE A SMALL TOROID CHOKE, HAS AT LEAST SIZE DIA.1.5 INCHES. TRY AWG#30 1200 TURNS.s

I am trying to understand how an inductive sensor works. I have the circuit diagram for a filter amplifier circuit. However I have an inductor and capacitor in parallel with eachother. I don't think it is to do with resonance because the inductor is being induced with a voltage using an electomagnet. Can anyone help with this??: It can be a very sharp filter to amplify only a narrow band of frequencies, determined by the resonant frequency of the LC. .s

An RLC circuit contains a 4.100e-6 F capacitor in series with an inductor. What should the value of the inductance be for a resonance frequency of 63.0 rad/s?Do we have to have the Equivalence Capacitance as 1/C, since the capacitor is in series?The formula for Resonance frequency is: omega 1 / (SQRT(L*C))where L ImpedanceC Capacitancebut Capacitance in series would be 1/4.1E-6 F which equals 2.44E5 F.Is this correct so far?OK if so, solving the resonance frequency for L would give: L 1 / C* omega^2omega 63 rad/s soomega^2 3969 rad/sso1 / (2.44E5 * 3969) 1.033E-9is right?! PLEASE HELP!!: Capacitive reactance, Xc 1/WC Inductive reactance, XL WL At resonace the capacitive and inductive reactance are equal. Xc XL Therefore, 1/W x C WL L 1/(W^2 x C) L 1/(63 x 63 x 4.1 x 10^-6) L 61.45 H. Wow! that's a big inductor. Are you sure W is correct?s

A 3.0A current passes through an inductor. If the inductor stores 19 J of energy, what is the inductance?A) 3.6 HB) 4.22 HC) 85.5 HD) 57 H: The energy stored is E(1/2)LI^2 where E: energy L: inductance I: current so L2E/I^2 L2*19/3^2 L4.22 Hs

I want to use this in an induction motor. (not a rotary phase inverter): Nope. Three phase is composed of three waves 120 degrees apart. Inductors can cause a 90 degree shift, but only between the current relative to the voltage.s

and what do you think its should resistance be: An inductor is a coil. It builds up an counter electromagnetic field that increases opposition to current flow as you increase current. The resistance is called inductance. It's variable depending on current pulled through it. Their good for things like filters because any spike in current is opposed by the built up field.s

I am working on a problem, and I have the solution, but there is a step that I'm having difficulty understanding.Given: Current in a 50 micro Henry inductor is iL18te^(-10t) amps, for t 0Find the voltage across the inductor.Here's the steps that are shown.VL(t) L(d/dt) * i(t)VL(t) [50*10^(-6) d/dt] * 18te^(-10t)VL(t) (9/10000)e^(-10t) - (9/1000)te^(-10t)What I don't understand is this last step. How do you get 9/10000 and 9/1000? Could someone please explain this?: The 9/10000 is just another way of writing 50e-6 x 18 x 10 in the first term and 50e-6 x 18 in the second term. Do you understand that you are differentiating t x e^(-10t) and that you apply the chain rule? You get 10 e^(-10t) + te^(-10t). Each of these terms is multiplied by the constant 50e-6 x 18.s
