In ac circuit power is dissipated in
WebTherefore, cos φ = 0, and no power is dissipated even though a current is flowing in the circuit. This current is sometimes referred to as wattless current. Case (iii) LCR series circuit: In an LCR series circuit, power dissipated is given by Eq. (7.38) where φ = tan –1 (X c – X L)/ R. So, φ may be non-zero in a RL or RC or RCL circuit.

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 quantity X C is analogous to resistance in a dc circuit in the sense that both quantities are a ratio of a voltage to a current. As a result, they have the same unit, the ohm. Keep in mind, however, that a capacitor stores and discharges electric energy, whereas a …
WebThe power factor for the circuit, overall, has been substantially improved. The main current has been decreased from 1.41 amps to 994.7 milliamps, while the power dissipated at the load resistor remains unchanged at 119.365 watts. The power factor is much closer to being 1: P F = P S P F = P S. WebPower dissipation takes place only in the resistor in an AC circuit. For a series LCR circuit at resonance, a purely resistive circuit is given as: ϕ = 0 ∘ It is represented as, P a v V r m s I r …
