Power consumed by heaters connected in series

  1. 1. The problem statement, all variables and given/known data

    Q20-9. The power rating of a 1480 W heater specifies the power consumed when the heater is connected to an ac voltage of 120V. What is the power consumed by two of these heaters connected in series, connected to the same voltage?

    I am a little new to the electricity field of physics, any assistance would be greatly appreciated.
    My first guess was that the power would be twice as much, but that is incorrect (2960 W)

    What equations do you know that relate voltage to power? Did you know that when in series the voltage is split between the components.
