Electric Motor The goal of this experiment is to build a simple electric motor and observe how it works. I will attempt to make it spin evenly by attaching it to a battery via jumper cables. The independent variable is the battery charge (1.5 V) and the dependent variable is how fast the motor spins. The lab doesn’t have multiple experiments for us to test this but I would hypothesize that the two variables would have a positive correlation: higher voltage‚ faster spin. I built my tiny motor

You rub balloons in your hair and then hang them like in the picture below. Explain why you think they move apart and what might affect how far apart they get. They move apart because they become charged while you are rubbing them in your hair and the charges are the same on both balloons. The more charges you get on the balloon

V=V (Ra + R1) 0.75A = (Ra + R2) 0.25A (Ra + R1) 3 = Ra + R2 3Ra + 3R1 = Ra + R2 2Ra = R2 – 3R1 Ra = 0.5(R2 – 3R1) 3. In a simple series circuit a battery is connected through an ammeter to an electric lamp. A voltmeter is connected parallel to the lamp. The ammeter reads 0.75 A and the voltmeter 50 V. What is the resistance of the lamp neglecting the current drawn by the voltmeter? If the current in the voltmeter is 0.001 A for each volt it indicates

Globalization at General Electric Case Directions: Develop a detailed corporate profile and address the questions in the case. General Electric‚ the company that Thomas Edison founded‚ and now the largest industrial conglomerate‚ in America produces a wide array of goods and services‚ from medical equipment‚ power generators‚ jet engines‚ and home appliances‚ to financial services and even television broadcasting (GE owns NBC‚ one of America’s big three network broadcasters).

Background: The Electric Motor Works (EMW) was Siemen’s primary producer of low wattage alternating current (A/C) motors‚ which sales volume was contributed by 80% of standard motors and 20% of customized motors. Although the firm had started to alter their program and had expanded the business in 1974‚ they still could not decline the price sufficiently to compete with the lower labour rate in Eastern Bloc competitors. Instead of mass production‚ EMW changed their strategy to manufacture efficiently

Introduction The merger case between General Electric Co. (GE) and Honeywell Inc. has sparked considerable debate between US antitrust agencies‚ economists and scholars since the announcement of its unsuccessful attempt by the European Commission (EC). GE is a corporation active in aircraft engines‚ financial services‚ and transportation systems while Honeywell is a manufacturing company producing aerospace products and is the leading supplier for engine starters. Both parties are from the US

Case Study: Immelt and the reinventing of General Electric Posted on July 29‚ 2011by Bruno Mognayie This case study was part of a strategy assignment taken at the SDA Bocconi School of Management. I’d like to thank my fellows Gouri Wagle‚ Felipe dell’Oro‚ Andrea Masina‚ Paolo Cerchiario‚ Ashna Suri-Sasmal and myself for the insights that contributed to put through this work. The issue: In September 2009‚ Ge’s Board of Directors reappointed Jeff Immelt as CEO. My team was asked to prepare a memo

Consumers wanted a three hundred mile range and eighty-five mile per hour speed on their electric cars but this was not plausible when running off of a battery. a.ii. When customers compare cars they don’t care much about the environmental risks they only care about the price‚ the miles per gallon‚ and the mileage range. Customers had a difficult time seeing the difference between regular cars and electric cars so there was not enough demand. b. Battery Technology (not guilty) b.i. Batteries

Electric cars are seen as the future of human life. They provide an oppurtunity of being clean and eco-friendly. Electric car motors are magnificent and figuring out how they work is a mystery. Electric cars have also been around for a while since almost two decades ago. Electric cars are proven to be better for the environment. Electric cars are a prime example of how electricity has changed over the years. First‚ electric cars are amazing‚ but what is more amazing is the motor that makes one
