  • Question

  • What is the current flow through R1, R2, and R3?

    What is the current flow through R1, R2, and R3? 1A, 1A, 1A 1A, 2A, 3A 3A, 3A, 3A 3A, 2A, 1A V = IR


  • Options
  • A. 1A, 1A, 1A
  • B. 1A, 2A, 3A
  • C. 3A, 3A, 3A
  • D. 3A, 2A, 1A

  • Correct Answer
  • 1A, 1A, 1A 

    Explanation
    V = IR

    V = I(R1 + R2 + R3)

    I = V/(R1 + R2 + R3)

    = 9/(3 + 3 + 3)

    = 9/9

    = 1 Amp.
