The teacher and researcher went into the room next door that contained the electric shock generator box. The generator has a row of switches marked from 15 volts (Slight Shock) to 375 volts (Danger: Severe Shock) to 450 volts. The teacher (subject) would read the list of words and then test the learner’s (confederate) memory. The experimenter would administer an electric shock each time the learner (confederate) responded incorrectly. The…
In the cell Cu (s) + Cu2+(aq) ↔ Cu2+ + Cu(s) ,when the concentration of Cu2+ was reduced from 1.0 M to 0.010 M, it caused the reaction to shift to the right. The standard E value was 0.00 Volts, the reaction shifted right and so did the E cell value. It got higher than the standard value as it attempts to reestablish equilibrium. According to LeChatliers principle, “When any system at equilibrium is subjected to change in concentration,…
To do Cable calculation it has to meet the requirements from BS 7671. Design Current First thing to do is calculate the design current. (Ib) I=Watts/Volts. You do this so you can find out the total current. Apply Diversity Factors (where applicable) Diversity is described in the onsite guide Appendix A as a way to determine the maximum demand for an installation and includes the current demand for commonly used equipment. For example if in a domestic household there were 8 lights on a…
The resistors R1, R2, RD, and RS calculated in the Prelab section were used to connect the circuit as shown in Figure 8-5. A load resistance RL of 10kΩ was used. The values of VD, VG, VS were measured and recorded. 3. The voltage vout was measured using an oscilloscope and the voltage gain AVG-D = vout/vin was calculated. The input voltage was adjusted if the output waveform was distorted. 4. The function generator was varied to obtain the necessary data to plot a frequency response curve for…
1.1 Dielectric Materials Dielectric materials are insulating materials that exhibit the property of electrical polarization. Dielectric materials support charge by acquiring a polarisation in an electric field. 1.1.1 Electric susceptibility and permittivity When a capacitor with capacitance C0 is filled with a dielectric material, its charge storage capacity (capacitance) increases to a value of C. Than susceptibility (χ^') of the dielectric materials is given by χ^'= (C-C_0)/C Dielectric…
Grade 9 Term 2 Science Assessment: Electromagnets Lab Report sheet Name: Greg Gerald Class: 9A Date: December 3 2015 Group Member: Dennis I. Research Question How did the amount of volt affect the strength of the electromagnets? Reason I wanted to know if an electromagnet can be strengthen even more through the increase of its energy. II. Introduction: What is electromagnet? Electromagnet is a magnet that runs on electricity. Electromagnet is created when a copper wire…
Locate your Jumper Cables. Locate your battery under the hood and find the battery’s positive and negative terminals. The positive terminal should have a red cover or can be signified by a + sign. Making sure none of the clamps touch one another, attach the red clamp to the dead battery’s positive terminal. Do not attach the black clamp to the battery’s negative terminal as it could cause hazardous sparks. Attach the other red clamp to the charged battery’s positive terminal, and then attach…
the Chevrolet Volt concept, an electric car. However, the 2008 recession, which led to a severe credit crunch, was hard on GM which was in need of working capital. It was able to receive a loan from the government, but under the condition that it would accelerate tough restructuring measures. The General Motors Corporation filed for bankruptcy in 2009, and a new, leaner, General Motors Company was incorporated to acquire its strongest assets. GM’s worldwide brands today include Chevrolet, Buick…
General Motors is an American success story. They started at the dawn of the 20th century, with a humble origin story; Buick began with horse drawn buggies, before starting its foray into the automobile market. For years it grew and expanded gobbling up smaller companies and incorporating them into its family. Just under one hundred years later, the state of General Motors’ empire started to deteriorate (which is directly due to a criminal lack of quality control). Then the housing bubble…
