Q:A variable inductor with negligible resistance is connected to an ac voltage source. By what factor does the ?
X wL where X is the inductor's Reactance and w is the frequency in rads/sec the reactance will increase by 6 x 8 48 so the current will decrease by the same factor
Q:Inductor and florescent in a series?
Calculate inductive reactance by formula X(L) 2 (pi) f L 2 *3.14 * 57.3 * 0.595 214.57 ohm Applied voltage 93.5 v. By Kirchoff;s law, this equals voltage drops in R and XL I*XL + I*R93.5 But these 2 voltages have phase difference of 90 deg so they must be added vectorially we know I*R 26.9 I*XL (93.5 ^2 -26.9^2)^0.5 i*XL89.54 i89.54/214.57 0.41733 Amp
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.
Q:What is concept behind Inductor? How does turns increase magnetic flux and then to end in Lenz law or whatever?
An inductor is an energy storing component in electrical circuits. In an inductor, the magnetic flux linkage (coupling) takes place. So, naturally more the no. of turns, more is the flux linkage, as more effective area (No. of turns*cross section) is available. The flow of current in an inductor induces a magnetic field. Lenz's law says that the flux induced in the inductor tends the oppose the very cause producing it. This simply means, that an inductor(i.e. the flux induced in it) tends to maintain the magnitude direction of current(which produces that flux) constant opposes any change in it.
Q:What is the current of the inductor?
Inductive reactance X(L) wL Current I voltage V/X(L) With the given increases, X(L) is multiplied by 12, so I decreases to 1/12 its initial value.
Q:Current of an Inductor - Physics Question?
Ohm's law still applies only this time you are working with inductive reactance instead of resistance. XL 2 pi f L V I XL I V / XL f 660 Hz; L 0.075 H; V 64 V Plug and chug!!
Q:An inductor is to be made by wrapping wires around a paper tube of radius 0.702 cm and length 8.44 cm. How m.?
Q:What is the rms value of the current through the inductor?
I v/Z Z Xl in this case as r0 Xl 2 Pi f L 2 * 3.14 * 60 * 5 I 110 / (2 * 3.14 * 60 * 5) 0.058 A
Q:240 V at 50 Hz applied to an inductor yields a current of 4A calcuate the maximum stored energy during a cycle?
Assuming the current is 4 amps RMS the impedance is j60 ohms, so the inductance is .191 H. The peak current is 1.414*47.07 amps The peak store energy is .5 L Ip^24.77 joules. There is 0 average power consumed by a lossless inductor.
Q:Inductor connected to AC source?
Use the equation X 2pi*f*L. You are given X indirectly, through V and I. Since I V/X, X V/I. Once you solve for X you can put this in the first equation and solve for f. X V/I 149/.83 179.52 X/(2pi*L) f 179.52/(2pi*.004) 7142.797 Hz
