WebOct 15, 2024 · If a resistor is placed across the live and neutral wires, the voltage across the resistor is alternating and thus, the current through the resistor is alternating. It's completely irrelevant to this result if the neutral wire is at 0V with respect to ground. But the wire isn't. You are applying 240v ac to the wire. WebNov 27, 2024 · In an ac circuit, there is a phase angle between the source voltage and the current, which can be found by dividing the resistance by the impedance. The average power delivered to an RLC circuit is affected by the phase angle. The power factor ranges from –1 to 1. 15.6 Resonance in an AC Circuit
