WebMay 22, 2024 · This implies that the power factor is unity at resonance. Also, in a real world circuit \(R\) is the combination of the series resistance plus any resistance from the inductor's coil. We can derive a formula for \(f_0\) as follows. The definition declares that the magnitude of \(X_L\) must equal the magnitude of \(X_C\). Therefore, we can set ... WebThe energy stored in the magnetic field of the inductor, L I 2 / 2, also decreases exponentially with time, as it is dissipated by Joule heating in the resistance of the circuit. Figure 14.14 Time variation of electric current in the RL circuit of Figure 14.12 (c). The induced voltage across the coil also decays exponentially.
The effect of an inductor in a circuit is to oppose changes in current through it by developing a voltage across it proportional to the rate of change of the current. An ideal inductor would offer no resistance to a constant direct current; however, only superconducting inductors have truly zero electrical resistance.
