Senan Farrelly Alec Haas Introduction Ohm’s Law is V = I * R or in some cases I = V / R. The next two laws were established by a German physicist by the name of Gustav Kirchhoff. Kirchhoff’s first law is his voltage law. Kirchhoff’s Voltage Law (KVL) states that around any loop in a circuit‚ the voltage rises must equal the voltage drops. The next law that Kirchhoff introduced was his current law. Kirchhoff’s Current Law (KCL) states that the total current entering a junction must equal the

individual’s self. Milgram created a threatening shock generator with starting level of 30 volts and expanding up to 450 volts. The experiment was set up with having an experimenter‚ a participant who was the subject‚ and a confederate pretending to be a volunteer. The teachers were told to ask questions from the learners and every time they gave a wrong answer‚ an electric shock was given and was increased 15 volt on each wrong answer. As the experiment advanced‚ the participants heard the learners argue

Why would people obey a legitimate authority figure even if they were asked to do something that was clearly and morally wrong? Hypothesis Milgram want to test the GADH (German’s Are Different Hypothesis)‚ which was currently being used by historians to explain the systematic destruction of millions of Jews‚ Poles and other’s in the 1930’s and 1940’s.

batteries were invented over 2‚000 years ago. The invention discovered in Baghdad in 1932‚ might have just been used for jewelry making. Real progress of storing electric current was made again in the late 18thcentury‚ when Alessandro Volta (after whom volt was named) shelved discs soaked in salt solution between zinc and copper plates to create electric current. This formed the base for the battery technology. Present The first wet cell batteries (like automobile) and dry cell batteries (like the remote

Milgram found that most participants resented verbally but obeyed behaviourally and 65 per cent gave the learner the maximum shock of 450 volts even though the teacher was complaining after only 100 volts. Therefore this research shows that under certain circumstances some people are willing to go against their conscious. Also he found out the fact that people will obey when someone who is a dominance in a social hierarchy

The details of power supply are not shown in a circuit symbol. 1.1.2 Infinite Open Loop Gain From Fig.1.1‚ it is found that vo = - Ao × vi‚ where `Ao’ is known as the open-loop gain of the opamp. Let vo be -10 Volts‚ and Ao be 105. Then vi is 100 :V. Here 2 the input voltage is very small compared to the output voltage. If Ao is very large‚ vi is negligibly small for a finite vo. For the ideal opamp‚ Ao is taken to be infinite in value. That means‚ for an
