A certain voltage divider consists of three 1 kΩ resistors in series. Which of the following load resistors will have the least effect on the output voltage?
Correct answer: A. 1 MΩ
- A. 1 MΩ
- B. 100 kΩ
- C. 1 kΩ
- D. 330 Ω
Explanation
A load affects a divider least when its resistance is much greater than the divider's output resistance. Of the choices, 1 MΩ draws the least current and causes the smallest voltage drop.
