- Q: Hello there everybodyI wanted to ask a question related to resistor capacitor and inductor connected togetherwhat if one of them is in series and the other are in parallelwhat if an inductor is connected in parallel and a resistor and a capacitor are in series.how can i calculate the equivalent resistanceisimply cannot understand the relation between all the three components
- There are many sites on the internet which explain a.c. theory. It is unrealistic to expect anyone to transcribe it here. Search fro electronics forums.
- Q: I understand that power is that rate at which work is done and that because of this the power is equal to d/dt (1/2Li^2). I also understand that the power is also equal to Li di/dt since Ldi/dt is v and v*i is power. I understand that since the power is equal to both of these equations that they are equal to each other. The part that I don't get is mathematically how to get from one to the other.
- you have written the steps yourself, from what i can tell d/dt [ (1/2)Li^2 ]. L is constant, i d/dt [ q(t) ], not constant using the power rule for differentiation d/dt [ (1/2)Li^2 ] (2)(1/2)Li*(di/dt). implicit differentiation if that step did not make sense, review the calculus techniques from first semester calc,, i dq/dt v -dΦ/dt -d/dt ( BAcosθ ) || B || (μ0 / 4π) * i visualize the charge (q) running through wire approaching inductor, as it flows into the coil, a B-field is induced, which tries to resist the CHANGE in current, this is where the work occurs
- Q: and whyalso does that work when you open circiut a capacitor.
- An ideal inductor appears as a short to DC. Real inductors have some resistance due to the wire they are wound with. Remember the voltage across an inductor V L di/dt if I is constant V 0. An ideal capacitor will appear open to DC. It will charge up to the DC voltage that would appear across it if it were not in the circuit (thevenin voltage). Ic CdV/dt. if V is constant Ic is zero. Electolytic capacitors have some leakage current.
- 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.Here's the figure:
- I(1/L)*integral(V dt). Note that you need to consider the initial conditions, when finding the solution. Once you get the solution, just plutg in t21ms.
- Q: An inductor is plugged into a 120V /60Hz wall outlet in the U.S. Would the peak current be larger, smaller, or unchanged if this inductor were plugged into a wall outlet in a country where the voltage is 120V at 50Hz ? Explain.
- higher frequency means higher reactance, which means lower current.
- Q: Any idea please. Thanks
- Read this in detail.
- Q: If a series RC, RL, or resistor-inductor-capacitor (RLC) circuit was given to you in a black box (with access only to the two input terminals), how could you determine the component values?
- w 2pi*f 2pi*60 377 rad/s Z R + j(wL - a million/wC) the place j sqrt(-a million) (in case you do no longer comprehend this line, pass directly to the subsequent) |Z| sqrt[R^2 + (wL - a million/wC)^2] |Z| sqrt{4.84e4 + [377*27e-6 - a million/(377*16e-6)]^2} sqrt[4.84e4 + (a million.02e-2 + a million.66e2)^2] 275.6 ohms (word thet the inductor seems especially very like purely a chew of cord with L0) Then rms i one hundred twenty/275.6 0.435A answer
- Q: If the voltage waveform is applied across the terminals of a 5-H inductor, calculate the current through the inductor. Assume i(0) -1A.
- since t 0.use equation I(t) Im * e ^ (-tR/L) if it sdischarging or if its charging, replace (e^(-tR/L)) with (1-e^(-tR/L)). It depends on the circuit though
- Q: I need a good description for my studies i know they are transformers i know they change current to high voltages/low voltages .In your best words can you describe a inductor.As you can see im still trying to understand the principals of one
- An inductor (or reactor or coil) is a passive two-terminal electrical component used to store energy in a magnetic field. An inductor's ability to store magnetic energy is measured by its inductance, in units of henries.
- Q: A 9.5 H inductor carries a current of 1.8 A. At what rate must the current be changed to produce a 60 V emf in the inductor?
- properly it exchange into meant to be a parody of the grey Mans face it is submit whilst human beings have not created their avatar. i had to do a sort of three-D matalic form mask of the old 'smiley' face they used to have yet they replaced it in the previous I had the possibility. I had to extend this one from a print out from a working laptop or computing device cafe in spite of the fact that it wasn't too sparkling. I comprehend now I could have taken the enlarged define around to a eating place returned and then re-worked the drawing from an avatar on the seen exhibit unit.
