Answer» e figure observe the following things :R₁ , R₂ and R₃ are in parallel .R₁ = 5R₂ = 10R₃ = 30Calculate the equivalent resistance 1/R = 1/5 + 1/10 + 1/30= > 1/R = ( 6 + 3 + 1 ) / 30= > 1/R = 10/30= > 1/R = 1/3= > R = 3Given potential difference = 12 vTotal current ( I ) = V/R= > 12 / 3= > 4 ACURRENT through each RESISTOR V = I R= > I = V/RNow V remains constant for all RESISTANCES.Now : I = 12 / RI₁ = 12/5= > I₁ = 2.4 AI₂ = 12/10= > I₂ = 1.2 AI₃ = 12/30= > 0.4 AANSWERS :The total current is 4 AThe resistances in each resistor is 2.4 A , 1.2 A and 0.4 AThe total resistance is 3 ohms |
