Yes, it is possible to replace resistors joined in series by an equivalent single register.

Example: Suppose there are three resistors of 1Ω, 2Ω and 3Ω connected in series.

So, if we want to attach only one resistor instead of these three resistors then we and add these resistors ie.

1Ω + 2Ω + 3Ω = 6Ω

Thus, we can place a single equivalent resistance of 6Ω instead of these three resistors.
