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.
The omnipresent usefulness of Ohm's Law: [ Voltage (volts) = Current (amps) X Resistance (ohms) ] Ohm's Law can be used with resistors to find the current flowing through a circuit. The law is I = V/R (where I = current, V = voltage across resistor, and R = resistance). For the circuit above we can only use Ohm's law for the resistor so we must use the fact that when the LED is on, there is a 1.9 voltage drop across it (BTW: The voltage drop varies with the type of LED).
