Closing Case: Planning for the Chevy Volt 1. What does the Chevy Volt case tell you about the nature of strategic decision making at a large complex organization like GM? From the Chevy Volt case‚ we can see that GM is a large complex organization and has a lot of processes to make any decision in changing their strategic plan. Moreover‚ they sticked to the past failure that they had experienced. Therefore‚ they moved too slow and missed the opportunity to change or adapt themselves to the external

current (I) through the resistor. Do this for a number of settings on the power pack‚ for example do two‚ four and six volt settings. (Remember the power pack should only be turned on while doing readings.) 2. Vary the voltage and record the potential drop (V) and the current (I) through the resistor. Do this for a number of settings on the power pack‚ for example do two‚ four and six volt settings. (Remember the power pack should only be turned on while doing readings.)

the capacitor levels out the DC voltage‚ producing a steady voltage inflow to the voltage regulator. The voltage regulator is crucial‚ as the phone only needs five volts to charge‚ whereas fast pedaling can produce 30 volts or more‚ which is enough to fry the average cell phone. The regulator controls the voltage‚ putting a five-volt ceiling on the power entering the phone. Results: Starting with a dead cell phone‚ plugged in and placed in a porch‚ one can spend approximately three hours and 25

Battery Desulfator Errata In my battery desulfator article on page 84 of HP77‚ the value for C2 should have been 0.0022 ìF‚ not 0.022 ìF. My mistake. I have put up a Web page that will give more details to help you build and use the desulfator circuit. I will place updates there‚ and will add a guestbook soon to allow comments and questions to be posted. I encourage a group effort in this‚ since I don’t have all the answers. Thanks.

Free Ohm's law Electric current Electrical resistance
Planning In this piece of coursework‚ I am going to investigate what affects the resistance of a piece of wire. Wire is made up of atoms. Electric current is a flow of electrons‚ and it is these electrons that collide with the nucleus of the atoms. Every time this happens‚ it causes resistance. The build up of friction is what produces the heat. There are many variables that could affect the resistance of the piece of wire: Length Potential difference Tension Temperature Diameter

the resistance (Ω) decreases As wire resistivity (Ωcm) increases‚ the resistance (Ω) increases Procedure Part II: Ohm’s Law: Electricity‚ Magnets‚ and Circuits Ohm’s Law mA is milliamps‚ and 1000 milliamps equals one Ampere. Move the potential (volts) and resistance (ohms) sliders and observe the current (amps) As voltage increases‚ current increases. As resistance increases‚ current decreases.
