Instantaneous current to phasor
Nettet17. okt. 2024 · Example 6: The instantaneous values of current and emf in an ac circuit are I = (1/√2) sin 314t amp and E = √2sin (314t – π/6)V respectively. The phase difference between E and I will be. Solution: We know that, Phase difference relative to the current, φ = (314t – π/6) – (314t) = – π/6 Nettet7. apr. 2024 · In phasor, the sine wave is converted into cosine. Hence, the sine wave with an amplitude of 2 can be written as: 2 sin(ωt) = 2 cos (ωt-90). As this is a pure resistive circuit the impedance (Z) is pure resistance; therefore, Z = R, the imaginary part phase is 0, as it is the real value.
