So the open source a,b voltage is easily seen as a series voltage divider to be 6 volts. Simply, thevenin's theorem states that any linear network with several power sources, resistances and a variable load can be represented in a much simpler circuit containing a single voltage source (v th) (known as thevenin's equivalent voltage) in series with a resistance (r th) (known as thevenin's equivalent resistance) and the variable load, where v th is the open.
