- Q: Current through an inductor is turned on at time t0, as shown in the figure. Vscos(200*pi*t). Calculate the energy delivered to the inductor at t21 ms.
- I'm sorry I confused you; the initial condition is 0. The current is .024 amps at 21 ms, so the energy is 10.94 uJ.

- Q: Ex. Negatively charged vinyl strip touches sphere of an electroscope. What happens to the leaves and positions of charges?
- Then, positive charges interact with the negatively charged inductor Good luck!
- Q: If an inductor carries 100mA DC of current when connected across a 30V DC source, then what is its resistance?
- I V / R R V / I R 30 / 100e-3 300 ohms The fact that is an inductor does not matter in presence of dc voltage. When non uniform voltage is present then this DC resistance will still be there, but there will be frequency dependent effect as well.
- Q: All the current from the wire before it will go through the inductor because there is no resistance, right?
- Almost. If it is made of very low ohmic value.
- Q: Any idea please. Thanks
- An inductor is a passive two-terminal electrical component which resists changes in electric current passing through it. It stores its energy in the form of magnetic energy, as opposed to a capacitor which store energy in the form of electrical energy. When current through an inductor is increased or decreased, the inductor resists the change by producing a voltage between its leads in opposing polarity to the change. This resistance increases as the frequency of AC current increases. If you have any further queries, please feel free to PM me.
- Q: Hi, I'm working on homework. The circuit has three inductors, L1, L2, amp; L3, in parallel with a resistor, R. I already know to calculate the total inductance when the inductors are in parallel. The problem is part B of the question has added another inductor in series with L1, L2, L3, amp; the load, R.I don't know how to figure L total in a series-parallel inductor combination circuit.
- JUST ADD L4 VALUE TO THE LAST RESULT.
- Q: does it slow down the current or stops the current into the coil?
- An inductor delays a change in current (so to speak). If an inductor is connected to a d.c. source through an open switch; at the instant the switch closes, full votage is applied across the inductor, but current does not flow due to a phenomon referred to as reverse electromotive force or reverse voltage. As a magnetic field builds in the inductor, current begins to flow, with the magnitude of current gradually increasing until the magnetic field builds completely. The inductor then acts as a short circuit. The time delay is a function of circuit resistance multiplied by inductance. At the instant the switch opens, the current in the inductor continues to flow until the field begins to collapse, at which point the current gradually reduces to zero.
- Q: An ac circuit has a 20 ?F capacitor, an 80 mH inductor, and a 60 Ω resistor in series. If the voltage source has an angular frequency of 1000 rad/s, what is the phase constant for the circuit?
- First calculate the reactance of the inductor and capacitor XL ωL 1000*80x10^-3 80Ω XC 1/ωC 1/(1000*20x10^-6) 50Ω So the phase constant φ arctan((XL - XC)/R) arctan((80-50)/60) 26.6o
- Q: i cant say no lol
- Damn that scandal that you found yourself smack dab in the middle of 15 minutes ago! I never believed it anyway. You and that Bieber chick playing Nude Twister on top of Wal*Mart? Never boughtnever bought it.
