Document Summary
*review session for the midterm (professor away for a conference)* Example 1: parallel resistors: 1/req = 1/r1 + 1/r2 + 1/r3 , series = req: r1 + r2 + r3 o. Example 2: careful addition of resistance in parallel and series. Capacitance is capacity to store charge of a given voltage: farther apart -> less potential, c = eoa/d, q = cv. Decreases v for given q - dielectric: c/co = k(capa, e = keo. Electric potential: noted by v , units: volts, scalar field that fills the space. Electric potential energy: noted by u o, property of a system of changes. Electric potential: v, volts, scalar field, circular lines of potential around charge. Capa 1 q1 negative: two neutral metal spheres, #1 and #2, are mounted on insulating supports. The wire connecting the spheres is removed and the charged rod is then taken away.
