Question

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 C4

I 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 1

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.
