An 11V power source provides supply to a 42 resistor that is connected to a paralle! combination of 12 resistor and 72 resistor. The 72 resistor is also connected to a parallel combination of a 22 resistor and 32 resistor. The 32 is connected to 13V voltage supply. Sketch the Norton equivalent circuit and find the current, voltage and the power that is dissipated in the 22 resistor using the Norton theorem.
