Current lag voltage
WebApr 14, 2024 · In a circuit, the current lags behind the voltage by a phase difference of \\( \\pi / 2 \\), the circuit will contain which of the following.(1) Only \\( R \\)(2)... WebMay 30, 2024 · Current and voltage start from the same physical phenomenon, electromagnetism, but they are totally different effects. In the inductance, being a coil, a magnetic field is generated by circulating a current through it. This current is maintained if the voltage to the coil is suddenly stopped.
