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.
