What this handout is about. This handout will explain what literature reviews are and offer insights into the form and construction of literature reviews in the humanities, social sciences, and sciences.
Parallel resistance is illustrated by the circulatory system. Each organ is supplied by an artery that branches off the aorta. The total resistance of this parallel arrangement is expressed by the following equation: 1/R total = 1/R a + 1/R b + ... 1/R n. R a, R b, and R n are the resistances of the renal, hepatic, and other arteries respectively.
1 For example, a circuit has two resistors in parallel, each with 4Ï resistance. 2  1 / RT = 1 /4Ï + 1 /4Ï â 1 / RT = 1 /2Ï â R T = 2Ï. 3  In other words, two branches of equal resistance are exactly twice as easy to get through as one branch alone. 4  If one branch has no resistance (0Ï), all the current goes through that branch.
