For example: if the transformer has a 480 volt primary and the available line voltage is running at 504 volts‚ the primary should be connected to the 5% tap above normal in order that the secondary voltage be maintained at the proper rating.

assigned to be a learner and a teacher. Milgram created an electric ’shock generator’; it ranged from 15-450 volts. The teachers were given a task to teach and then test the learner on a list of word pairs. For the first wrong answer‚ the teacher will flip the switch labeled "15 volts". If the learner continues making mistakes‚ he will moved to the next higher level‚ with the maximum of 450 volts. If the teacher obey‚ he will hear the learner shriek in apparent agony as you continue to raise the shock

Set the Oscilloscope’s “Volts/Division” knob for “channel 1” to 2V/DIV‚ and set the sweep “Seconds/Division” knob to 0.2 ms/DIV. 2- Set the coupling switch (AC/DC/GND) to GND and move the trace to the middle of the screen. When you finish set the coupling switch to AC again.

many potatoes does it take to light a 0.70-volt bulb or three (3) 0.24-volt bulbs? Is it possible for potatoes to be utilized to sustain the electricity we have today? II. Hypothesis a. Null Hypothesis ( H0) Potatoes are ineffective sources of electricity as it cannot produce enough voltage to light a 0.70-volt bulb. b. Alternative Hypothesis (Ha) Potatoes are effective sources of electricity as it can produce enough voltage to light a 0.70-volt bulb. III. Materials And Procedure

highest concentration (1.5 mol dm-3 ) was the lowest out of the 3 trials at 1.68 volts‚ thus proving that the higher concentration the lower the voltage. When the concentration of the product decreases‚ it will drive the equilibrium to the right to minimize the impact. Although‚ the lowest calculation (0.5 mol dm-3) is not necessarily the highest out of all 3 trials‚ it is not far off from 1 molar solution‚ only 0.2 Volts.

violations found in the original experiment (1962) included participants (teacher) giving other participants (learner) dangerous electrical shocks at a very high voltage increasing all the way up to 450 volts. The experimenter (authority) informed both the teacher and the learner participants that although the volts may be painful‚ they are not dangerous. Even though the “teacher” could hear the “learner” yell and scream as they got shocked each time‚ the “teacher” continued with the experiment because the

None of the volts were real‚ but the learner acted as if they were so the participant believed they were shooting electric volts through the learner. Milgram carried out this study to see how far someone would go when given instructions by an authority figure. At 150 volts the learner demanded to be released his heart’s starting to bother him now‚ at 180 the

Stanley Milgram carried out one of the most famous studies of obedience in psychology. He was a psychologist at Yale University‚ conducting an experiment that focused on the conflict between obedience and morality. It showed that people have a strong tendency to obey with authority figures. Milgram was interested in researching how far people would go in obeying an order even if it involved harming another individual. He was fascinated on how easily ordinary people could be influenced in committing

0-5v volt. The output of sensors in terms of milli volts‚ then the milli volt output will be amplified with the help of the suitable amplifier. Then the amplified signal will be in the range of 0 to 5 volts. Then it will be given to the ADC (analog to digital converter)‚ this will convert the analog voltage into digital data. The ADC‚ which we are going to use is ADC0809‚ it is an eight channel eight bit ADC. This will produce 00H (00000000B) for 0 voltage and FFH (11111111B) for 5 volts.
