Resistors are electronic components that limit the flow of electrons through a circuit. The electrical resistance of a resistor is measured in Ohms. A certain type of resistor is advertised to have an average resistance of 100 Ohms. A sample of 20 resistors is selected and gives a mean resistance of 102.4 Ohms and sample standard deviation of ? = 5.1 Ohms. Assuming resistance is Normally distributed, is there evidence to suggest the average resistance of this type of resistor is not 100 Ohms. Answer this question by performing the appropriate hypothesis test using an alpha-level of 0.05.

To automatically insert electronic components in printed circuit boards for a cell phone production line, a $500,000 surface mount placement (SMP) machine is being evaluated by a manufacturing engineer at Motorolla. Over the 10-year planning horizon, it is estimated the SMP machine will produce annual cost savings of $92,500. The engineer estimates the machine will be worth $50,000 at the end of the 10-year period. Based on the firm’s 10% MARR, how long does it take for the new SMP...

± Analysis of Electroplating When electricity (the flow of electrons) is passed through a solution, it causes an oxidation-reduction (redox) reaction to occur. If the solution contains a metal cation such as Ag+, the flow of electrons will reduce the silver ion, causing solid silver to plate onto the electrode. The amount of metal plated depends on the number of electrons passed. The total charge of a mole of electrons is 96,485 coulombs (C) and 1ampere(A)=1coulomb/second(C/s) 19/20 MC Part A...

Consider a simple electrical circuit where you charge a capacitor through a resistor by connecting a battery (closing the switch) at time t=0. The charge Q on the capacitor is related to the current I by dQ/dt=I. Furthermore, by Kirchhoff’s law, V – RI – Vc =0, and the charge Q on the capacitor is Q=CVc, where C is the capacitance. That can be combined to give the differential equation dQ/dt = V/R - Q/RC The analytic solution is Q(t)=CV(1...
