a) 4.0 ohm parallel

b) 4.0 ohm in series

c) 2.4 ohm in parallel

d) 2.4 in series

e) 9.0 in parallel

My work: A, 1/12 + 1/4= 1/3 or 3 ohm resistance

By using only two resistors, R1 and R2, a student is able to obtain resistance of 3 ohm, 4 ohm, 12 ohm, and 16 ohm using the alone combination. The values of R1 and R2 (in ohms) are:

A) 3,4

b) 2,12

c) 3, 16

d) 4, 12

e) 4, 16

My answer is d 4,12. Since 4 is alone, 12 is alone. in series 12+4=16 and in parallel the value is 3.

thank you

correct.
