Add the two together. For instance, two 100 ohm resistors in series have a total resistance of 200 ohms.
Just add the individual values together for the total resistance of two resistors in series.
each resistance drops the same current so the wattage disipated would be 2times the single one.
It means the two resistors have same resistance
I observe that the total effective resistance of several resistors in series is the sum of the individual resistance values of the individual resistors.
You can connect 4 resistors in series-parallel, i.e. two in series, both in parallel with another two, and the effective resistance would be the same as one resistor. Similarly, you can connect nine resistors in 3x3 series-parallel, or 16 resistors in 4x4 series-parallel, etc. to get the same resistance of one resistor.
The more resistance there is, the harder it is for current to flow. So the total resistance is the sum of all resistors in series.
That depends ... in a very interesting way ... on whether they are connected in series or in parallel. -- If the resistors are in series, then the total resistance increases when you add another resistor, and it's always greater than the biggest single one. -- If the resistors are in parallel, then the total resistance decreases when you add another resistor, and it's always less than the smallest single one.
Two eight-ohm resistors in series would have a total resistance of 16 ohms. Two eight-ohm resistors in parallel would have a total resistance of four ohms.
The total resistance of resistors in series is simply the sum of the resistance values of those resistors. If the resistors are identical, then you can multiply the resistance of one of them by the number of resistors in the circuit.

The resistance of two or more resistors connected in series is the sum of the individual resistances. (If any of the connections between them is sloppy and involves some resistance at the connection, then that also has to be added in.)
The net resistance of two resistors connected in series is the sum of the two resistances. RSERIES = Summation1toN RN

Two resistors in parallel are equivalent to a single component with a lower resistance than either of the pair. Two resistors in series are equivalent to a single component with a resistance equal to the sum of the pair, therefore a higher resistance. For a given potential difference, more current in total will flow through two resistors in parallel than through the same resistors in series.
The more resistance there is, the harder it is for current to flow. So the total resistance is the sum of all resistors in series.
