    If anyone is good at this, please complete, will be hugely appreciated.

    OK so for the circuit attached;

    Using super positioning theory, calculate the following:

    1. The current flowing in the 10 Ohms resistor.

    2. The power dissipated in each of the resistors in the circuit.

    This is the last question i need help with, please help me.

    use star-delta transformations to transform the delta combination of resistors
    20, 20 and 10 Ohms to a star combination and you will be able to solve it

    for the 10 ohm resistor, it gets really easy when you start shorting the sources for superposition.

    The 5V source contributes nothing (the terminals of the resistor are shorted
    The 20V source is in parallel with the resistor.
    The 10V source is in parallel with the resistor.
