Steady-state circuit om de energieopslag van de inductor te vinden

How does a steady state inductor work?

In the steady state, part of the reactive power is supplied by the inductor. That is, energy stored in the magnetic field associated with the inductor is swapped back and forth with the electric field associated with the capacitor, reducing the amount of reactive power to be supplied by the voltage source. The new apparent power is

Do inductors appear as shorts at steady-state?

At steady-state, inductors appear as shorts. (9.3.2) (9.3.2) At steady-state, inductors appear as shorts. This is the opposite of what was seen with capacitors. For example, in the circuit of Figure 9.3.1 , initially L L is open, leaving us with R1 R 1 and R2 R 2 in series with the source, E E.

What is the current through an inductor?

The inductors themselves are ideal, and have a resistance of 0 Ω. Thus, the current through each inductor should be 4 2 = 2 A. However, my textbook seems to disagree and says that the current is 8 3 A. I am aware that XL = ωL, but that is for an AC circuit and not a DC circuit.

Is an inductor open or short?

This is opposite of the inductor. As we have seen, initially an inductor behaves like an open, but once steady-state is reached, it behaves like a short. For example, in the circuit of Figure 9.4.1 , initially L L is open and C C is a short, leaving us with R1 R 1 and R2 R 2 in series with the source, E E.

What is a steady-state equivalent circuit?

For the steady-state condition the capacitor will be fully charged, its current will be zero, and we treat it as an open. The steady-state equivalent circuit is drawn below in Figure 8.3.6 . Figure 8.3.6 : Circuit of Figure 8.3.3 , steady-state.

What is a steady-state alternating current?

The word steady-state means that the circuit frequency, phases of all voltages and currents, and amplitudes of all voltages and currents do not change over time. Transient effects are entirely excluded from our consideration. Similarly, the AC voltage and currents are called steady-state AC voltage and steady-state alternating current.
