Question

Find the dissipation factor when series resistance is 5 ohm and capacitive resistance is 10 unit.

(a) 2

(b) 0.5

(c) 1

(d) 0

I had been asked this question by my school teacher while I was bunking the class.

The origin of the question is Method of Images in section Electrostatic Boundary Value Problem of Electromagnetic Theory

Answer 1

Right answer is (b) 0.5

The best I can explain: The dissipation factor is nothing but the tangent of loss angle of loss tangent. Tan δ = Series resistance/Capacitive resistance = 5/10 = 0.5.
