Two voltage sources and two loads, how to approach this one

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

    2. Relevant equations


    3. The attempt at a solution

    Should I just consider that A and B are parallel with each voltage source respectively and so therefore that's the voltage drop that they experience individually?

    The ground terminal should be zero volts, no? Wouldn't that mean the polarity of the bottom voltage source needs to be reversed?

    You could try applying KVL for both the loops and obtain something you'll need to calculate the power consumed by each appliance
    I'm not completely sure about this though.

    Seems right to me.
    Zero potential is a convention. What matters is potential difference. The PC does not care which side you choose to call zero.
