so I'm just trying to reduce this circuit into 1 resistor and the current source. The dots indicate nodes, which I'm not sure makes a difference...



so can I combine R1, R2, and R3 in series
then, R4 and R5 in parallel?



Then can I combine those two resistors in parallel assuming that they are parallel?

          The ground node has got you confused.



          How much current flows in the ground?



          Why treat R4 and R5 different to R1 R2 R3?

                    White Anglo-Saxon Protestant

                    Image
                    White Anglo-Saxon Protestants ( WASPs ) are a social group of wealthy and well-connected white Americans, of Protestant and predominantly British ancestry, who trace their ancestry to the American colonial period. Until at least the 1960s, this group has dominated American society and culture and dominated in the leadership of the Whig and Republican parties. They usually are very well placed in major financial, business, legal and academic institutions and had close to a monopoly of elite society due to intermarriage and nepotism. [1] During the latter half of the twentieth century, outsider ethnic and racial groups grew in influence and WASP dominance weakened. Americans are increasingly criticizing the WASP hegemony and disparaging WASPs as the epitome of "the Establishment". The Random House Unabridged Dictionary (1998) says the term is "Sometimes Disparaging and Offensive". [2] [3] The term WASP is often used as a pejorative to classify their historical dom...

                    Conflict (narrative)

                    Image
                    Conflict in narrative comes in many forms. "Man versus man", such as is depicted here in the battle between King Arthur and Mordred, is particularly common in traditional literature, fairy tales and myths. [1] In works of narrative, conflict is the challenge main characters need to solve to achieve their goals. Traditionally, conflict is a major literary element that creates challenges in a story by adding uncertainty to if the goal would be achieved. A narrative is not limited to a single conflict. While conflicts may not always resolve in narrative, the resolution of a conflict creates closure or fulfillment, which may or may not occur at a story's end. Contents 1 Basic nature 2 Classification 2.1 Man against man 2.2 Man against nature 2.3 Man against self 2.4 Man against society 3 History 4 See also 5 References 6 External links Basic nature Conflict in literature refers to the different drives of the characters or forces involved.
