    Resistors in series:

    • The sum of all the voltages over the resistors equals the potential of the source.
    • The current going through the resistors is the same in all the resistors.

    The power dissipated in each resistor equals the current through the resistor multiplied by the potential ...

    Solution Summary

    The solution demonstrates how the different configurations affect the power dissipation in the resistors.
