Answer 1

First let us find the resistances of the resistors R₁ , R₂ ,  

we know V = i x R

it can be obtained from the slope of the V vs i graphs of the corresponding graphs.

so R₁ = tan(30°) = 1 / √3 ; R₂ = tan(60°) = √3 ; R₃  = tan(45°) = 1.

Now when the switch s is closed ,

equivalent resistance of the circuit can be given by  

⇒$Req = R2 + \frac{1}{\frac{1}{R1}+\frac{1}{R3} }$

⇒  $Req = \sqrt{3} +\frac{1}{\sqrt{3} +1}$

⇒Req = 2.098 Ω  

so the current through the circuit i = V / Req

⇒ i₁ = 120 / 2.098 = 57.195 amp

now when the switch s is open the equivalent resistance

Req = √3 + 1 = 2.732 Ω      

so the current through the circuit = 120 / 2.732

i₂ = 43.923 amp  

so ,

i₁ : i₂ = 1.3

HOPE THIS HELPS YOU !!

Answer 2

First let us find the resistances of the resistors R₁ , R₂ ,

we know V = i x R

it can be obtained from the slope of the V vs i graphs of the corresponding graphs.

so R₁ = tan(30°) = 1 / √3 ; R₂ = tan(60°) = √3 ; R₃ = tan(45°) = 1.

Now when the switch s is closed ,

equivalent resistance of the circuit can be given by

Req = 1 / [ 1 / ( R1 + R3 ) ] + R2

⇒Req = 2.098 Ω

so the current through the circuit i = V / Req

⇒ i₁ = 120 / 2.098 = 57.195 amp

now when the switch s is open the equivalent resistance

Req = √3 + 1 / √3 = 2.309 Ω

so the current through the circuit = 120 / 2.309

i₂ = 51.961 amp

so ,

i₁ : i₂ = 1.1 : 1

(hey there here is the corrected answer it went wrong in my above answer).
