- Q: A 94 mH inductor is connected to a outletwhere the rms voltage is 127 V and the frequency is 42 Hz.Determine the energy stored in the inductorat t 8.9 ms, assuming that this energy iszero at t 0.Answer in units of J
- Do inductors store energy? Man! I dont think so!
- Q: A 265 mH inductor whose windings have a resistance of 6.70 Ω is connected across a 10.5 V battery with an internal resistance of 3.35 Ω. How much energy (in J) is stored in the inductor?Thanks for the help!
- U Potential energy R Resistance 6.7ohms I current V/R (10.5V/6.7ohms) 1.57A L inductance 265mH .265H U (.5)LI^2 (given formula in any physics text book) U (.5)*(.265H)*(1.57A)^2 .33 J
- Q: hence it is an energy storage device
- Inductor In Dc Circuit
- Q: can I do a mutual inductance experiment using a boxed inductor or it should be an air-coil inductor?
- If you have 2 inductors that have mutual coupling, they could be either air coupled or coupled by a magnetic core. The package doesn't matter.
- Q: An inductor has an impedance of 31.0 Ω and a resistance of 20.5 Ω at a frequency of 47.5 Hz. What is the inductance? (Model the inductor as an ideal inductor in series with a resistor.)? (in mH)
- Impedance Z √(R? + X??) 31? 20.5? + X?? X? 23.25 ohms X? 2πfL 23.25 2π(47.5)L L 0.0779 H or 78 mH .
- Q: I have simple rl circuit two resistance in parallel and a inductor - 5 H in parallel. I need to thevenize the circut but I do not know how to handle with the inductor, wich is in value of 5 Hplease help thank you
- let's see what we can find :-) (by the way, what does thevenize mean? I've never heard of that before)
- Q: An inductor is connected to an AC generator.As the generator's frequency is increased, what happens to the current in the inductor?The current increases.The current decreases.The current does not change.Don't just choose one, explain why you choose it.
- The frequency of the generator is given via here equation, Frequency(velocity*form of poles)/a hundred and twenty So the two boost the fee or the form of poles to get bigger frequencies.
- Q: Fo 1/2pi x sqr LC
- The Resistance of an inductor is not really called the parasitic resistance. It is called the intrinsic resistance. A parasitic element is an element that changes the intrinsic properties of the device by adding or subtracting from them (typically adding). A parasitic resistance of an inductor would be the solder resistance (which is usually small and negliable). The relationship of the Resistance to the Reactance of the inductor is known as the Q and is expressed as Q X / R, where X is the inductive reactance. The Q is also a definition of the -3dB bandwidth and determines the bandwidth from -3dB rolloff points from the center resonance frequency (fo). So where the resistance R is very small in relation to the Reactance X, the Q is high and the bandwidth is narrow (sharp Q). So where the resistance R is very large in relation to the Reactance X, the Q is low and the bandwidth is wide (flat Q).
- Q: A series RLC circuit is connected across a 10kHz source. The 1.2 H inductor and 1000 ohm resistor are fixed and the capacitor is variable. At what capacitance will the current in the resistor be a maximum?
- At resonance, the current is at its maximum value. The aim of this problem is to have a resonant circuit and in order to do so, the condition for resonance is: Reactance of the Inductor Reactance of the Capacitor 2*PI*f*L 1/(2*PI*f*C) cross multiplying. (2*PI*f)*(2*PI*f)*L 1/C solve for C. C 1/(4*(PI^2)*(f^2)*L) C 1/(4*(PI^2)*((10 x 10^3 Hz)^2)(1.2 H)) 2.1109 x 10^-10 Farad ANSWER
- Q: A 9.5 H inductor carries a current of 1.8 A. At what rate must the current be changed to produce a 60 V emf in the inductor?
- properly it exchange into meant to be a parody of the grey Mans face it is submit whilst human beings have not created their avatar. i had to do a sort of three-D matalic form mask of the old 'smiley' face they used to have yet they replaced it in the previous I had the possibility. I had to extend this one from a print out from a working laptop or computing device cafe in spite of the fact that it wasn't too sparkling. I comprehend now I could have taken the enlarged define around to a eating place returned and then re-worked the drawing from an avatar on the seen exhibit unit.
