Question

In a series LCR circuit, the measured voltages satisfy Vʟ = 2Vᴄ and Vᵣ = Vᴄ. Which statements are correct?

G1 Physics · Accepted Answer

The net reactive voltage is Vʟ − Vᴄ = Vᴄ, equal to Vᵣ. Therefore tanφ = 1, so |φ| = 45° and power factor = 1/√2. Since Vʟ > Vᴄ, the circuit is inductive. The source voltage is √2 Vᴄ, not 2Vᴄ.
