    The resistor dissipates 1 W when two identical batteries are connected in series.

    Explanation:

    Power dissipated is directly proportional to the Voltage and Current.

    Connected in series, the total voltage of two batteries is equal to the sum of the voltage of each one.

    If I double the applied voltage, the dissipated power will be double.

    P = V*I
