KCET2011PhysicsCurrent Electricity
In the circuit shown, the currents i₁ and i₂ are
Options
- Ai₁=1.5 ~A , i₂=0.5 ~A
- Bi₁=0.5 ~A , i₂=1.5 ~A
- Ci₁=1 ~A , i₂=3 ~A
- Di₁=3 ~A , i₂=1 ~A
Correct answer
B. i₁=0.5 ~A , i₂=1.5 ~A
Step-by-step solution
Resistance R= 12 4 12+4 +2= 48 16 +2=5 Electric current I= E R+r = 12 6 =2 ~A gathered I₁+I₂=2 ~A I 1 R I₂=1.5 ~A , I₁=0.5 ~A gathered
