- Q:Physics Question on Faraday's Law and Inductors?
- The natural (resonant) frequency (fₒ) of a LC circuit is given by . fₒ 1/(2π√LC) Find the value of C that gives a frequency 6.90^6 Hz . (fₒ)² 1/(4π²LC) C 1/(4π²L.fₒ²) . C 1/(4π² x 1.07^-6H x [6.90^6Hz]²) . . ►C 4.97^-10F (0.497pF/0.50pF)
- Q:What is the maximum magnitude current across inductor in LC Circuit?
- you in addition to mght prefer the frequency. the internet impedance is the sum of XL and XC which cancel out, so that's going to be inductance under resonance, capacitance above resonance and intensely low at resonance in a sequence circuit. No resistance is a mathematical abstraction, does no longer exist often talking, because it would desire to contain infinity, however the question is incomplete.
- Q:Circuit question of inductor and resistor?
- A) the reactance of the inductor is XL 2π*f*L 2π*1350*0.590 5005Ω So the impedance Z sqrt(1150^2 + 5005^2) 5135Ω Therefore the rms current V/Z 12.1V/5135Ω 2.36x10^-3A 2.36 mA B) If the current is reduced to 1/2 then then impedance must double So Z sqrt(R^2 + (XlL- XC)^2) 10270 So 1150^2 + (5005 - XC)^2 10270^2 or 5005 - XC +-sqrt(10270^2 - 1150^2) +-10205 or XC 5005 + 10205 15210 Now XC 1/2πf*C or C 1/(2π*1350*15210) 7.75x10^-9F 7.75nF
- Q:Physics question about inductors?
- Jag tycker det är lustigt hur du ska översätta detta för att se vad jag skrev. Läser du fortfarande här? Du borde sluta nu.
- Q:An RLC circuit contains a 4.100e-6 F capacitor in series with an inductor. What should the value of the induct?
- 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?
- Q:An air-filled cylindrical inductor has 2600 turns. It is 2.4 cm in diameter and 28.5 cm long. (a) What is its?
- hyperphysics.phy-astr.gsu.edu/hba a) Solenoid length 28.5 cm with N 2600 turns, Coil radius r 1.2 cm gives area A 4.52389 cm2. Relative permeability of the core k 1 (air) Then the inductance of the solenoid is B 0.013484 Henry 13.484 mH. b) Number of turns 2600 / √ 1700 63 turns hyperphysics.phy-astr.gsu.edu/hba Goodbye
- Q:Inductors and Scope Waveform?
- When you turn the current off, you are forcing the current to be zero in a short time. Since: V L x (rate-of-change of current), the voltage will go negative for the short time that the current changes from it's steady value to zero. When you turn the circuit on, you should initially see the full (open circuit) voltage of the battery. I imagine this is the spike you see. After a short time, the current reaches the battery's limit, and the voltage will drop. If the battery is fresh, you should see the spike at about 9V, and then it will drop to a steady value that is less than 9V. Current is being limited by the battery's internal resistance. Hope this helps.
- Q:What is the inductance of the inductor?
- The reactance is 22/10ma 2200 ohms Xʟ 2πfL 2200 2π(5000)L L 0.070 H or 70 mH .
- Q:what are the inductors in a motherboard for ?
- inducting heat so the suader dosent melt
- Q:A 45-mH ideal inductor is connected in series with a 60 ohm resistor through an ideal 15- V-DC power supply an?
- The time constant T is T L/R. So for your problem T 45x10^-3H/60 Ohm 7.5x10^-4 s Now the current in the curcuit after a very long time is simply I0 V/R 15/60 0.25 A. The current as a function of time is given by I(t) I0*(1 - e^(-t/T)) set t 7x10^-3 and solve for I I 0.25 A* (1 - e^(-7x10^-3/(7.5x10^-4))) 0.2499 A the current has been flowing for almost 10 time constants which means it is almost at full value.
