The output voltage of a charger is__________?
Correct answer: B. higher than the battery voltage
- A. less than the battery voltage
- B. higher than the battery voltage
- C. the same as the battery voltage
- D. none of the above
Explanation
The charger must provide a voltage greater than the battery's terminal voltage so that charging current flows into the battery. If it were equal to or lower, effective charging would not take place.
