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. WebIn a purely resistive circuit, all circuit power is dissipated by the resistor (s). Voltage and current are in phase with each other. In a purely reactive circuit, no circuit power is dissipated by the load (s). Rather, power is alternately absorbed from and returned to the AC source. Voltage and current are 90° out of phase with each other.

WebFigure 32.2. Single-loop AC resistor circuit. The current I is thus equal to (34.3) Equation (34.3) shows that the current oscillates in phase with the emf. The power dissipated in the resistor depends on the current through and the voltage across the resistor and is therefore also a function of time: (34.4) WebFeb 4, 2024 · The power dissipated at resonance in the LCR circuit: At resonance X C – X L = 0 and φ = 0. In this case, cos(φ) = 1. Thus, the power dissipated in this case is maximum. … option is sci
