What is the expression for the loss angle?(a) tan⁡ δ = ωR4(b) tan⁡ δ = ωR4 C4(c) tan⁡ δ = ωC4(d) tan⁡ δ = R4 C4I had been asked this question during an online interview.I'm obligated to ask this question of Schering Bridge in division Measurement of Inductance and Capacitance of Electrical Measurements

Answer»

Right option is (b) tan⁡ δ = ωR4 C4

To explain: The expression for the loss angle can be COMPUTED as the RATIO of the TANGENT of the voltage drop across resistance RX to the voltage drop across the capacitance Cx.
