You do not have to put in the arrows showing the flow of electrons. 1. a) Three cells in parallel, two light bulbs in series, with one switch b) Three cells in […]
a) Explain what is meant by the following terms with respect to electricity: Current, charge, work, power, resistance and voltage. b) If I increase the resistance in a circuit and the voltage remains the same, what happens to the current? Which law does this reflect? The circuit diagram shows a 12V dc supply of negligible […]
Watch the following videos on the now famous Milgram Obedience Experiment, conducted over 50 years ago (you may need to copy and paste these addresses into your browser: Discuss the following questions: – Why did the majority of people follow the instructions to increase the voltage? – If such an experiment would inflict real pain […]
