At balanceR2=4.8Ω R3=2000Ω R4=2850Ωand C2=0.5μF and r2=0.4ΩThe dissipating factor of capacitor C1 is ______ ×10−3.7.34
Answer» The four arms of a bridge are: arm ab : an imperfect capacitor $C_{1}$ with an equivalent series resistance of $r_{1}$ arm bc : a non-inductive resistance $R_{3}$ arm cd : a non-inductive resistance $R_{4}$ arm da : an imperfect capacitor $C_{2}$ with an equivalent resistance of $r_{2}$ in series with $R_{2}$ . A supply of 450 Hz is given between terminal a and c and the detector is connected between b and d. At balance $R_{2} = 4.8 Ω R_{3} = 2000 Ω R_{4} = 2850 Ω$ and $C_{2} = 0.5 μ F$ and $r_{2} = 0.4 Ω$ The dissipating factor of capacitor $C_{1}$ is ______ $\times 10^{- 3}$ . 7.34
