A pair of 1-ohm resistors connected in series has a combined resistance of
A)1 ohm.
B)2 ohms.
C)1/2 ohm.
D)none of the above

Question

Quizplus · Accepted Answer

When two resistors are connected in series, their resistances add up to give the total resistance. Therefore, in this case, the combined resistance of the two 1-ohm resistors connected in series will be 1 + 1 = 2 ohms. The other choices (A and C) are not correct because they are either too low or too high for the combined resistance of two 1-ohm resistors in series. Therefore, the best choice is (B) 2 ohms.
