The following arrangement consists of an ideal transformer and an attenuator which attenuates by a factor of 0.8. An ac voltage V_wx1 = 100V is applied across WX to get an open circuit voltage YZ1 V across YZ. Next, an ac voltage V_YZ2 =100V is applied across YZ to get an open circuit voltage V_WX2 across WX. Then, V_YZ1 / V_WX1 , V_WX2 / V_YZ2 are respectively, GATE ECE 2013 Network Theory - Network Theorems Question 22 English

Two magnetically uncoupled inductive coils have Q factors q₁ and q₂ at the chosen operating frequency. Their respective resistances are R₁ and R₂. When connected in series, their effective Q factor at the same operating frequency is

q₁ + q₂

(1/q₁) + (1/q₂)

(q₁R₁ + q₂R₂)/(R₁ + R₂)

(q₁R₂ + q₂R₁)/(R₁R₂)
