- Q: An inductor has a 42.0 reactance at 60.0 Hz. What will be the maximum current if this inductor is connected to a 50.0 Hz source that produces a 110 V rms voltage?1 A
- 42 what? ohms? 42 ohms at 60 Hz means at 50 Hz it is (50/60)42 35 ohms current 110/35 3.14 amps RMS peak current 3.14 x 1.414 4.44 amps .
- Q: A capacitor and inductor with the same reactance connected in parallel cancel out each other (open circuit), right?
- are you talking about the mains power supplies and correction capacitors? they only alter the phase relationship between current and voltage. many industrial machines have high inductance, altering the phase of the current. the correction caps put them back into phase.
- Q: If you double the current through an inductor, what happens to the inductance of the inductor?It is doubled.It remains the same.It is halved.
- Inductance of an inductor does not depend on either voltage or current. It is a constant quantity just as resistance! The only way to decrease or increase inductance is using parallel and series combinations of inductance respectively
- Q: A 215 ? resistor and a 0.2 H inductor are connected in series with an AC source of 234 V and frequency 106 Hz. (a) What is the current in the circuit? (b) Calculate the phase angle between the current and the voltage of the AC source. I have tried every way possible to find the correct answer, which is a) 0.925A and b) 31.8 degrees, couldn't figure it out. Your help will be greatly appreciated. Thank you!
- Reactance of inductor (X) is given by X 2πfL X 2 * π * 106 * 0.2 X 133.2 ? Impedance (Z) of circuit: Z √(R? + X?) R 215?; X 133.2 ? Z 252.92 ? Ohm's Law i v/r I 234 / 252.92 I 0.925 A Voltage across R is in phase with the supply voltage, so phase angle arctan(X/R) arctan (133.2 / 215) 31.78°
- Q: After the switch in the following circuit has been closed for a long time (tinfinity), what is the current through L1?Also, after the switch in the circuit in the circuit has been open for t500 microseconds, what's the current through L2?How do i find the current? Please show me or give me instructions how as this will help me in the future.
- the current initially is 10v / 500 ohms 0.02 amp When you open the switch, the current will eventually decrease to 10v / 1000 0.01 amp It decays exponentially from the initial to the final value with a time constant, T, of L/R 0.25 / 1000 250 usec i(t) 0.01 + 0.01 e^(-t / T) i(500) 0.01 + 0.01e^(-500/250) 0.01 + 0.01e^(-2) 0.01135 amp
- 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 6.0 and the driving frequency is increased by a factor of 8.0?
- 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: if electric field is zero then how current passes through an inductor?
- the inductor is a coil of metal The E field inside is zero because it acts like a faraday shield. Within the metal if its a pure inductor there is no resistance. (copper losses zero) so a finite current is driven by a zero E field. (OK thats hard to comprehend, but only because a PURE lossless inductor is imposible)
- Q: At a given instant the current through an inductor is 50.0mA and is increasing at the rate of 115 mA/s. What is the initial energy stored in the inductor it the inductance is known to be 60.0mH, and how long does it take for the energy to increase by a factor of 10 from the initial value?
- Energy in an inductor 0.5 L I^2 0.5 (60 x10^-3)(50 x10^-3)^2 7.5 x10^-5 J 7.5 x10^-4 J 0.5 (60 x10^-3) I^2 I SQRT [ 7.5 x10^-4 J / 0.5 (60 x10^-3) ] 1.58 x10^-1 Amps 158mA increase needed 158mA - 50mA 108mA time 108mA /115mA/s .939 sec
- Q: If the current through an inductor were doubled, the energy stored in the inductor would be1. doubled.2. the same.3. halved.4. quartered.5. quadrupled.
- E 0.5 L i^2 the energy would be increased by 2^2 or quadrupled answer 5
- Q: and is increasing at the rate of 100 mA/s. a.) What is the initial energy stored in the inductor if the inductance is known to be 61.0 mH? Jb.)How long does it take for the energy to increase by a factor of 10 from the initial value? s
- If you look up inductor on Wikipedia, you'll find that. E?LI? Where Eenergy LInductance Icurrent So finding the energy isn't hard. To find the time for part b, first find the current needed for 10 times the enrgy (also using E?LI?, but this time with 10 times the energy). Then, if we assume that the rate of increase is constant (seems to be true from the problem statement) finding the time is a matter of dividing the current difference by the rate of change (the 100 mA/s).
