1. The problem statement, all variables and given/known data According to Ohm's law, the voltage V, current I, and resistance R in a current are related by the equation V = IR, where the units are . . . Assume the voltage is constant V = 12V. Calculate: a) The average ROC of I with respect to R for the interval from R = 8 to R = 8.1 b) The ROC of I with respect to R when R = 8 c) The ROC of R with respect to I when I = 1.5 2. Relevant equations I'm assuming something like f(x) = lim(h->0) of f(x+h) - f(x)/h or finding the f'(x 3. The attempt at a solution I'm not really even sure how to set this problem up. I have about a million problems with this homework set, have seen the teacher, have seen a tutor, nothing really seems to help.
