5 Safe Use and Care of Instruments skills will be practiced in this week and honed throughout the year) Continuity Tester Analog Multimeter (Focus on Demonstrations) Digital Multimeter Megger / Insulation Tester The Oscilloscope (Teacher to Set Up Instrument) Practical: Conduct simple continuity tests using the multi-meter. 6 Basic Atomic Theory Principles of Theory of current flow. (Electron flow vs. Conventional Electricity Current Flow) Resistive Characteristics of different materials Conductors, Semi Conductors, Insulators What is Conductor / Semi Conductor / Insulator 2-3 Examples of each and characteristics. No further theory needed A wire is a conductor, but not all conductors are made of wire (Electrical Shock and Safety) of Materials used as conductors: copper, aluminium, gold, silver, steel and nickel chrome wire. Specific resistance. (No Calculations) Negative and Positive Temperature coefficient. (No Calculations) 7 The Resistor What is a resistor Composition of Resistor Types of Resistor Tolerance (Indicated Value vs. Measured Value)(2% and 5%) Colour Code of Resistors (4 band and 5 Band resistors) Power vs. Size (1/8w, 1/4 W, 1/2 W, 2W and 5W) Measuring the Value of Resistors Calculating the Value of Resistors Potentiometer ( Construction, functional operation, symbols) Rheostat (Difference between a Potentiometer and Rheostat ( Construction, functional operation, symbols)
