add an independent current source with value 3A pointing down between points a and b. T hen
use series and parallel combinations to reduce this to a single node-pair circuit (or simpler) to find
the voltage across the 40 Ω resistor (+ reference on top). Then, " undo" the combinations (as in the
previous problem) to find the current down through the 20 Ω resistor (call this Io
