Two resistances Rl and Ri are connected in series across the voltage source where Rl>Ri. The largest drop will be across______________?

Correct answer: A. Rl

  • A. Rl
  • B. Ri
  • C. either Rl or Ri
  • D. none of them

Explanation

In a series circuit the same current flows through both resistances, so the voltage drop V = IR is greater across the larger resistance. Since Rl > Ri, the largest drop is across Rl.
