Problem 52E

Resistors to be used in a circuit have average resistance 200 ohms and standard deviation 10 ohms. Suppose 25 of these resistors are randomly selected to be used in a circuit. a What is the probability that the average resistance for the 25 resistors is between 199 and 202 ohms?

b Find the probability that the total resistance does not exceed 5100 ohms. [Hint: see Example 7.9.]

PHY 184 Week 6 Notes-Currents and Resistance 10/3-10/6  The battery produces a constant voltage  When closed the current is able to flow o Don’t forget only the electrons move  In the absence of an electric field electrons move randomly within the conductor o When an electric field is applied electrons get an additional velocity called drift velocity  It is 10 times slower than thermal velocity  How is it almost instant then o Closing the current starts an electric field and sets the electrons in motion Charge Carriers  Consider a conductor with cross section A and electric field E  Suppose there are n positive carriers per unit volume, all evenly distributed in the same dV with drift velocity v
