Yup. All the current.

So the wattage rating remains the same.

Since they're in series, each resistor sees only half the
voltage. So the wattage rating of the pair hasta double.
Just for example - two 20K half-watters in series makes a 40K @ 1 watt rating.
Just as two 20K half-watters in parallel makes a 10K @ 1 watt rating.
