Six resistors are in parallel. The two lowest-value resistors are both 1.2 kΩ. The total resistance______________?
Correct answer: D. is less than 600 Ω
- A. is less than 6 kΩ
- B. is greater than 1.2 kΩ
- C. is less than 1.2 kΩ
- D. is less than 600 Ω
Explanation
The two 1.2 kΩ resistors alone have an equivalent resistance of 600 Ω in parallel. Adding four more parallel branches can only reduce this value, so the total is less than 600 Ω.
