COMEDK2024PhysicsCurrent Electricity
The current drawn from the battery by the network of resistors as shown in the figure is
Options
- A1 A
- B2 A
- C0.5 A
- D0 A
Correct answer
B. 2 A
Step-by-step solution
The given circuit is equivalent to given below, Now, 1 2 = 2 4 i.e., P Q = R S The given circuit is a balanced Wheatstone bridge. The resistance of 5 in arm B D is ineffective. Now circuit can be drawn as Equivalent resistance, aligned R^ & =(1+2) |(2+4) & =3 | 6= 3 6 3+6 =2 aligned Current drawn from the battery, I= V R^ = 4 2 =2 ~A
