NEET 2021 Physics Current Division Rule MCQ Question
Type: MCQ-conceptual-Medium-Class 12
Three resistors having resistances r₁, r₂ and r₃ are connected as shown in the given circuit. The ratio i₃/i₁ of currents in terms of resistances used in the circuit is:
A
r₁/(r₂ + r₃)
B
r₂/(r₂ + r₃)
C
r₁/(r₁ + r₂)
D
r₂/(r₁ + r₃)
Correct Answer
Option B
Detailed Explanation
Using the current division rule, the current through r₃ is given by i₃ = i₁ * (r₂ / (r₂ + r₃)). Therefore, the ratio i₃/i₁ = r₁/(r₂ + r₃).
