To prevent a DC return between source and load, it is necessary to use___________?
Correct answer: C. capacitor between source and load
- A. resistor between source and load
- B. inductor between source and load
- C. capacitor between source and load
- D. either A. or B.
Explanation
A coupling capacitor passes AC while blocking DC, so it prevents a DC return path between the source and load. A resistor or inductor would not provide this DC isolation.
