Q:Physics Question on Faraday's Law and Inductors?
Why 2pi?
Q:A resistor and an inductor are connected in series to an ideal battery of constant terminal voltage.?
At t 0 , current is zero , so no voltage drop is on resistor and the whole supply voltage is applied to the inductor in order to maximize the current rate of rise.
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:What type of inductor should i use to pickup a signal from a passing magnet?
I found that the open frame unshielded wirewound inductors work great to create a magnetic field, thus would also be great to pick up a magnetic field. Anything from 100 uH up would work.
Q:What is the potential drop across the 15.0-mH inductor just after closing the switch?
An inductor is an open circuit at t0 and a short circuit at t∞. A capacitor is a short circuit at t0 and an open circuit at t∞. That makes things very easy. (a) At t0, all you have is a 75Ω in series with a 25Ω resistor. So the voltage on the bottom side of the 15mH inductor is +200V⋅²⁵⁄₂₅₊₇₅ +50V. There is no current in the 50Ω resistor, so no voltage drop, so the other side of the 15mH inductor is at +200V. So the voltage across the inductor is 150V at t0. (b) At t∞, all you have now is a 50Ω in series with a 25Ω resistor. So the voltage on the bottom side of the 70μF capacitor (there is no current in the 38Ω resistor) is +200V⋅²⁵⁄₂₅₊₅₀ +66⅔V. The voltage on the other side of the 70μF capacitor is +200V. So the voltage across the capacitor is 133⅓ V at t∞.
Q:A 100-turn, air-core inductor has an area of 200 square micro-meters and is 200 milli-meters long.?
Lmuo N^2 area/length where muo4 pi*10^(-7) and area is in meters squared and length is in meters. You can do the math.
Q:An LC circuit of a 4-mH inductor and a 200μF capacitor.?
In a RLC circuit w0 a million/sqrt(LC), fw0/(2*pi) (you could convert it from radians to hertz to get 352) w0 is the resonance frequency, it extremely is mutually as the resistance is lowest via making use of certainty the capacitor and inductor cancel one yet yet another out. So at ww0, the resistance is in ordinary terms R IV/R one hundred 55/10 15.5A i'm doubtful at what element you're on your reading, yet convert the two the inductor and capacitor into their impedance type Z. capacitor a million/(jwC), inductor jwL you could desire to apply calculus to discover the minimum of the series resistance (it is w0). and you will study that the impedance of the capacitor and inductor cancel out at this frequency.
Q:Inductors and Current Question?
for an inductor the energy is given by U (1/2) L i^2 , where 'i' is the current so that increase of energy dU (1/2) x 220 x10^-3 ( 0.8^2 - 0.35^2) 0.057 J (nearly)
Q:Simple electricity questions 10 pts Thank you?
1 )an inductor connected to a dc source, amount of current flow depends on a) dc resistance 2) an inductor in a circuit opposes d) all of the above 3) Placing an inductor in series with a lamp that is connected to AC souce wll cause the lamp to c) glow dimmer Dc resistance of an an inductor is always equal to the inductors reactance. false Dc resistance and reactance of an inductor have very different effecs in an AC circuit. True or false Hard to say about this one. They can be similar in that both oppose flow of current but can be different in the effect on the phase of the current. when dc is applied to an inductor only the inductor's reactance affcts current flow. False. The DC resistance also affects the transient and steady state current.
