PHIL 2170 Lecture Notes - Heterosexism

Describe the arrangment of circuit elements that is called a voltage divider and the relationship among the various potential differences for that arrangement.

An electron initially at rest accelerates through a potential difference of 1V, gaining kinetic energy (K.E.)_e whereas a proton initially at rest accelerates through a potential difference of -1volt, gaining kinetic energy of  (K.E)p. Which of the following relationship holds.

The diameter of wire A is greater than the diameter of wire B, but their lengths and resistivities are identical. For a given voltage difference across the ends, what is the relationship between P_A and P_B, the dissipated power for wires A and B, respectively? (a) (b) (c)
