- Q: A variable inductor with negligible resistance is connected to an ac voltage source. By what factor does the current in the inductor decrease if the inductance is increased by a factor of 2.0 and the driving frequency is increased by a factor of 6.0? ? x
- 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: a dc voltage source is connected to an inductor through a switch and then the switch is closed . at t 0 the inductor will behave as an open circuit . no current will flow and all the source voltage will be across the inductor. why is that? why the inductor has such behaviour. why no current can pass through the inductor at t0.
- At t0, switch closed and a potential came across the inductor. So it is like a Alternating current for a Moment. That alternating current makes inductor to behave like in AC circuit. That affects reduce continuously after t+ time because of dc voltage. There will a opposing electromagnetic field in the inductor due to sudden voltage. that will stop current to flow through the inductor
- Q: If the current through the inductor (L 34.8 mH) at 448 Hz has an amplitude of 55 mA, what is the amplitude of the AC voltage?What is the rms value of the AC voltage?
- Inductive Reactance X? 2πfL 98 ohms E I*X 55 mA x 98 ohms 5.39 volts The problem is, what do you mean by amplitude ? Voltages are measured in peak, peak-peak, or RMS. If none are stated, RMS is assumed. So lacking a meaning for amplitude, I have to assume they are in RMS current and voltage. So the RMS answer is 5.39 volts RMS. .
- Q: A circuit consists of a 17 ? resistor and a 510 mH inductor connected in series to a 16 V battery. What is the value of the current when the current is increasing at the rate of 8 A/s?Answer in units of A.
- hyperphysics.phy-astr.gsu.edu/hba the equation for I is given. dI / dt V/L e^(-tR/L) calculate dI / dt 8, you will find a value for t, plug is value for t into the equation for I
- Q: An inductor has an inductance of 0.075 H. The voltage across this inductor is 64 V and has a frequency of 660 Hz. What is the current in the inductor?
- X_L 2 π f L 2 * π * 660Hz * 0.075H 311Ω I V_L / X_L 64V / 311Ω 206mA
- Q: An inductor 2H is connected in series with a bulb with resistance 5ohms and 9v dc power supply and a time constant of 0.4sWhat is the voltage across the light bulb after 0.5s. ??
- Current (V/R)*(1 - e^(-t/T)) where t time, T time constant After 0.5 seconds I (9/5)*(1 - e^(-0.5/0.4)) Voltage current*resistance I*5 9*(1 - e^(-0.5/0.4)) Over to you and your calculator!
- Q: - Here's a look at the 2013 WWE Hall of Fame class and the latest word on who their possible inductors are: * Bruno Sammartino - Arnold Schwarzenegger * Mick Foley - Terry Funk or Jim Ross, or possibly both of them at the same time. * Bob Backlund
- Bruno Sammartino - Great World Champion * Mick Foley - Boring * Bob Backlund - Boring * Trish Stratus - Still Beautiful * Donald Trump - Illegal Alien with false Birth Certificate.
- Q: I have a very basic doubt on these topics.av power taken by these over complete cycle is zero.so does that mean a device made up of only L C wont consume any power.also if c l are there wats the point of using resistance thanpls hlp in detail.
- L and C simply store electricity in a magnetic field (L) or electric field (C), only to release that energy later. If L and C are perfect, then you're right, they won't consume power. Practically, though, a real L has some resistance, and a real C has some leakage (conductance, G). If you put DC across an inductor, it will short out, and overheat. If you add a resistor in series, the current will be limited by the resistor, and will not reach too high a current.
- Q: I am wanting to build an inductor to certain specs.The inductor will operate in the audo frequencies of about 5-20kHz and be wound on an iron core. I need an inductance of about 150mH.How do I determine what type of core I need, what wire size, and the number or turns of wire will be required to make the inductor?Any help or references will be appreciated!
- L u0 ur N^2 A/length Where L is the Inductance and u0 4pi x 10^-7 and ur is the relative permeability of the core material (which should stay constant with current fluctuations) and N is the number of turns and A is the cross sectional area of the core and l is the magnetic path length. . all in SI units. The wire size will depend of how much current the winding has to tolerate without getting too warm. DON'T DO IT! There are so many factors that you'll wish you had never tried. Buy the inductor you need from an electronics shop and make sure its power rating can cope. Don't use an iron core - it will not be able to cope with the higher audio frequencies. A powdered-iron toroid might be best
