In a series circuit with unequal resistances______________?
Correct answer: D. the highest resistance has the highest voltage drop
- A. the highest resistance has the most of the current through it
- B. the lowest resistance has the highest voltage drop
- C. the lowest resistance has the highest current
- D. the highest resistance has the highest voltage drop
Explanation
Current is identical through all components of a series circuit, so the current is not highest in the lowest-resistance element. Since V = IR, the highest resistance has the greatest voltage drop.
