by using friction. The guide told them ohms law. The tour guide gave them an activity to do to better understand a circuit; he gave rex 3 wires, one battery, and a light bulb. The guide was leading rex through the whole thing because he did not really understand. The guide told rex that he had been putting the wires on the wrong side of the battery. The guide explained why he needs to fix it; he told him that the circuit would need a positive and negative charge in order for it to work. On rex’s

Chapter 1 1. Introduction Resistance welding covers a wide range of specific processes, mainly use for highly automated or even fully mechanized welding application, the majority in mass production. All these processes, except one (ESW, electroslag welding), need a mechanical clamping and pressurizing system to compress the workpiece areas intended to be welded prior to welding. Thus, these welding applications are categorized as resistance pressure welding processes (See figure 1-1)

and his solution was to use a second electrolyte to consume the hydrogen produced by the first. Zinc sulfate may be substituted for the sulfuric acid. The Daniell cell was a great improvement over the existing technology used in the early days of battery development. A later variant of the Daniell cell called the gravity cell or crowfoot cell was invented in the 1860s by a Frenchman named Callaud and became a popular choice for electrical telegraphy. The Daniell cell is a type of electrochemical

fruit taste.Furthermore, each cup containing soil mixed with star fruit juice was associated with a series of copper wire and zinc plate, the electric current to flow.The result, electrical energy is created with a sizable voltage, ie up to 5 volts, enough to turn on the lights. The resulting voltage is also greater than the voltage of the battery stone fruit.According to him, electrical energy is created by starfruit has a high acidity level to be able to conduct ions and electrons are there on

instead of gasoline. Transportation will be pollution-free and versatile. “of the several converging trends for getting around, “ultracapacitors” are being developed for electric cars to completely replace batteries. They have lighter weight and ten times the energy density of lead-acid batteries. In the future energy portfolio, another surprising development is the permanent magnet powered motors, which are an emerging trend bound to come to market. A number of developments, such as the Spiral Wankel

signal conditioning unit (consisting of low noise amplifier, switch, microcontroller and power management chip) is ~ 36mW in the ON state and only ~7.2µW in OFF state (sleep mode). The test gas in this particular case was methane for which sensor resistance varied from 100KΩ to 10KΩ. This hybrid sensor system is very much suitable for detecting a single gas with display of corresponding gas concentrations and subsequent alarming if the threshold limit is crossed. Index terms: MEMS, Gas sensor, Low

while isolating those systems from each other; they are mainly use for monitoring systems. 2. Use Ohmmeter to measure resistance for DC motor used in this Lab. 56 omhs 3. In Activity 1, explain how you turned the DC motor “on” and “off.” I tried using a transistor as switch using a breadboard and a power supply (battery) to power the motor, with a 1k ohms resistor to limit current, I also connected a custom power supply to add 3.3v onto the breadboard. On our project the simplest way is the ON-OFF

ELECTROPLATING Introduction: Electroplating is the process of coating a metal object with another metal, using electrical current passed through a chemical solution. This process produces a thin, metallic coating on the surface of the metal object. The main purposes of electroplating are to improve the appearance of the material and provide protection against corrosion. This is done by hanging pieces of metal to be replenished in the solution. These metals are called anodes and the positive electrical
