Explanation / Answer

first of all question is not clear:

if we recall from resistance,

remember these about Combination of Resistors

if R1 and R2 are the resistances connected in series then effective resiatcne Rnet = R1+R2

if R1 and R2 are connected in parallel, then 1/Rnet =1/R1 +1/R2 or Rnet =   R1R2/(R1+R2)

same current passes through each of the ressitor in series combination and

same votage passes through eacf of the resistor in parallel combination

apply ohms law V = iR

where V = volatge and i = current

iam assuimg that , 4 and 24 in parallel, sp R' = 4*24/(4+24)

R' = 3.482 ohms

then 2 is in series with this, so Rnet = 3.482 + 2 = 5.482 ohms

--------------------------

another possibiliyt is that if all are in series,

then Rnet = 4+ 2+ 24 = 30 ohms
