A balanced Wheatstone bridge consists of four resistances arranged in a loop, where the ratio of adjacent arms is equal, resulting in zero current through the central galvanometer. If a circuit has four resistors each of 2 Ω forming the outer arms, and a 2 Ω resistor connected across the central bridge arm with a 2 V ideal DC voltage source applied across the main terminals, what is the value of the total current drawn from the source?
