WebA 20-mH inductor is connected across an AC source with a variable frequency and a constant-voltage amplitude of 9.0 V. (a) Determine the reactance of the circuit and the maximum current through the inductor when the frequency Is set at 20 kHz. (b) Do the same calculations for a frequency of 60 Hz. WebA really good example of this is the calculation power in a reactive circuit as shown in Figure 3. The real power (that which will be dissipated in the circuit) is related to the magnitudes of the voltage and the cosine of the phase angle between them. Apparent power is the simple product of the magnitudes of voltage and current.

WebThe current in an inductor cannot change instantaneously because it implies an infinite voltage will exist, which isn't going to happen. This reluctance to change is because of the … WebJun 13, 2024 · In the AC (sinusoidal) case, note that when the inductor emf is (instantaneously) zero, the inductor current isn't (instantaneously) changing, i.e., the … make my own gift certificate template free

WebQuestion: 1. In an AC series circuit, the current in a pure resistor differs in phase with the applied voltage by what angle? Options: a=zero, b=45°, c=90° d=180 2. In the inductor of a 60-Hz AC series circuit, the peak voltage precedes the peak current in … WebTo show what happens with alternating current, let’s analyze a simple capacitor circuit: ... As with the simple inductor circuit, the 90-degree phase shift between voltage and current results in a power wave that alternates equally between positive and negative. This means that a capacitor does not dissipate power as it reacts against changes ... WebGenerally, AC circuits contain resistors, inductors, and/or capacitors. Impedance, represented by the letter “ Z ” and measured in Ohms, is the total opposition that a circuit offers to the flow of AC current, and is a combination of resistance R … make my own game website for free
