When a 1.6 kΩ resistor and a 120Ω resistor are connected in parallel, the total resistance is____________?
Correct answer: C. less than 120 but greater than 100 Ω
- A. greater than 1.6 kΩ
- B. greater than 120 but less than 1.6 kΩ
- C. less than 120 but greater than 100 Ω
- D. less than 100 Ω
Explanation
A parallel combination is always less than its smallest branch resistance, so the result must be below 120 Ω. Calculating the combination gives about 111.6 Ω, which is greater than 100 Ω.
