Five 100 Ω resistors are connected in parallel. If one resistor is removed, the total resistance is______________?
Correct answer: A. 25 Ω
- A. 25 Ω
- B. 500 Ω
- C. 100 Ω
- D. 20 Ω
Explanation
Removing one of five parallel resistors leaves four 100 Ω resistors in parallel. Their equivalent resistance is 100/4 = 25 Ω.
