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.
