Current DivisionMediumQuestion 31635

Question

Two resistors R₁ and R₂ in parallel carry total current I. Current through R₁ is:
  1. A
    I×R₁/(R₁+R₂)
  2. B
    I×R₂/(R₁+R₂)
    Correct
  3. C
    I/2 always
  4. D
    I×R₁R₂

Correct answer

I×R₂/(R₁+R₂)

Explanation

Current divides inversely with resistance: I₁ = I×R₂/(R₁+R₂). Smaller resistance gets more current.
