Four resistors of equal resistance R each are connected. Which of the following values cannot be achieved by using all four?
A
2 R
B
1.33 R
C
0.25 R
D
2.5 R
Explanation
Using all four resistors, common values are 4R (series), 0.25R (parallel), R (two parallel pairs in series), but 2R requires only two resistors in series or specific bridge combinations.
