You have to replace 1500 Q resistor in radio. You have no 1500 Q resistor but have several 1000 Q ones which you would connect__________?
Correct answer: B. two in parallel and one in series
- A. two in parallel
- B. two in parallel and one in series
- C. three in parallel
- D. three in series
Explanation
Two 1000-ohm resistors in parallel give 500 ohms; adding a third 1000-ohm resistor in series gives 1500 ohms. Thus the required arrangement is two in parallel and one in series.
