Q: current under one volt?: Variable inductors are not used very often, but a powdered iron toroid could be used. I would be built something like an auto transformer. Most diodes have less than a volt when forward biased.

Q: Hi,I'm planning to build an audio amplifier and for the crossover, I've been looking in to using resistors instead of inductors?I know what each one does. Simply put resistors do not hold an electrical charge like inductors in an electromagnetic field.What is the role of the inductor in this circuit? I'm not asking for the definition, I'm asking what it's doing to the actual audio signal.Also I've put a capacitor in series for the top frequency and after trying it out with different caps, the audio gets distorted in the speaker component (the cone moves to its maximum rating). Am I right in saying that I'd need a bigger speaker, well a bigger speaker cone in fact, to increase the rating of volume and power of the signal to reduce distortion/noise?Thanks,Rish: capacitor resistor combinations are used as high and low pass filters networks, to shape a frequency response i;e you may want sounds up to 50hz amplified 200 times whereas above that you may want to attenuate them as higher sounds are obtuse to the human ear, so in an op amp circuit using a 10k going into a 2.2meg feedback resistor would achieve a theoretical gain of about 220, putting a 1.5 nfd capacitor in conjunction with a 220k resistor above the feedback, could be used to achieve this cut off point and reduce the gain at higher frequencies. be advised that the Xc of the capacitor used would reduce the overall gain down to 155 from the calculated 220 when ac is passed through an inductor the output voltage leads the current by up to 90 dergees, whereas a capacitor has the exact opposite effect. inductors are used in a parallel resonance circuit to produce a very high gain over a narrow bandwidth, it would be useful to see a circuit diagram LC circuit - Wikipedia, the free encyclopedia

Q: A series circuit consisting of an inductor of negligible resistance and a pure resistor of 12Ω is connected to a 30V, 50Hz AC supply. If the current is 2A, calculate: (a) the PD across the resistor (b) the PD across the inductor (c) the inductance of the inductor (d) the phase angle between applied voltage and current. (e) the impedance of the circuit: (a) PD 2A X 12 Ohm 24 Volts (b) Z 30V/2A 15 Ohm Xl (15 Ohm) X sin(arc cos 12/15) 9 Ohm PD across inductor 2A x 9 Ohm 18 Volts (c) 9 Ohm (6.28) x (50) x inductance Inductance 9 / 314 28.7mH (d) Phase angle arc tan Xl/R arc tan 9/12 36.87 degrees (e) Impedance 30V/2A 15 Ohm

Q: how do u calculate the SRF of a inductor,for example i have a 90Mhz oscillator,but i need a RF choke to block the RF from entering the other part of the circuit,so the SRF of the RF choke should be more than 90Mhz may be 110Mhz.,so how can i calculate the SRF,i make inductors by myself.so please help me out.: I was in The Corps right as Vietnam was ending and the rule against laying hands on recruits was not yet in place. It is nothing like it was but I've heard from some more recent marines that things still happen but nothing like it used to be. I saw a guy get spin kicked when standing at attention in the barracks by a DI who was some kind of a kung fu badass and saw a number of recruits get punched. I personally got punched in the gut pretty hard. I also saw a guy get led around by a string tied around his dick on the parade field with his pants around his ankles for screwing up a marching formation. FYI my platoon also had a guy jump from our 3rd story barracks down to the hard deckwe never heard if he lived or died, nothing was ever told to us and the DI's just went ahead with training like nothing had happened. Parris Island was not for the faint of heart back then.

Q: An inductor is plugged into a 120V /60Hz wall outlet in the U.S. Would the peak current be larger, smaller, or unchanged if this inductor were plugged into a wall outlet in a country where the voltage is 120V at 50Hz ? Explain.: higher frequency means higher reactance, which means lower current.

Q: For an ideal conductor in an ac circuit explain why the voltage across the inductor must be zero when the current is at the maximum: I would answer as i know: From equation V L (di/dt), it tells us something. The nature phenomenon of an ideal or any practical inductor is that it will protect current not to change rapidly.For example, if the current at first condition is 5 Amp. but suddenly you increase it to 6 Amp. the inductor will act aginst the change so it will increase by some amount of time not suddenly increase.The time depend on many factors-induction,etc. At the maximum point of waveform,the current is quite constant.So,it's not nessessary for the inductor to act against the current.The Vol. so would Zero. Does this help?

Q: An RL circuit consists of two inductors of self-inductance L1 10.00 H and L2 4.00 H connected in parallel to each other, and connected in series to a resistor of 6.00 ? and a battery of 4.00 V (See figure). Assume that the inductors have no mutual inductance. When the battery is suddenly connected what is the inital rate of change of the current in inductor L1?Figure:: For the best answers, search on this site

Q: At a given instant the current through an inductor is 50.0mA and is increasing at the rate of 115 mA/s. What is the initial energy stored in the inductor it the inductance is known to be 60.0mH, and how long does it take for the energy to increase by a factor of 10 from the initial value?: Energy in an inductor 0.5 L I^2 0.5 (60 x10^-3)(50 x10^-3)^2 7.5 x10^-5 J 7.5 x10^-4 J 0.5 (60 x10^-3) I^2 I SQRT [ 7.5 x10^-4 J / 0.5 (60 x10^-3) ] 1.58 x10^-1 Amps 158mA increase needed 158mA - 50mA 108mA time 108mA /115mA/s .939 sec

Q: capacitorinductorresistorabove devices work on what, ac current/voltage, dc current/voltage , bothgive answer for each in very very brief.also explain why capacitance of capacitor increases when dielectric is used in terms of electronic current and charges on plates and dielectric.: Very breifly: Resistors - a gadget that provides 'resistance' to cutting-edge pass. Capacitors - a gadget which could save a cost. Inductors - a gadget that opposes a metamorphosis in cutting-edge.

Q: At time t0, emf of 500V is applied to a coil which has industance of 0.7H and resistance of 40ohm. What is the energy stored in the magnetic field in the inductor when the current reaches one third of its maximum value?OMG im stuck on this, i don't know which formula to use.: 1kWh3.6*10^6 J SO 3kWh3*3.6*10^610.8*10^6 J Inductors save the flexibility in variety of magnetic field. power saved by using inductor0.5*L*I^2 10.8*10^60.5*L*I^2 21.6*10^6L*I^2 L21.6*10^6/(9*10^4) L2.4*10^2240 H (Unit of inductance is Henry)
