Experiment A:1) Fundamental of basic electrical instrument Objectives: Operate basic electrical laboratory tools (oscilloscope, function generator, DC power supply). Determine transistor type (NPN, PnP), terminals, and material using digital multimeter. Graph the collector characteristics of a transistor using experimental methods and determine. Determine the value of the alpha and beta ratios of a transistor. Construct series and shunt voltages regulator configurations. Calculate and measure Vout when input power supply Vin is changed while resistor load Rl is fixed and vice versa for voltage regulator circuit. Describe the difference of clipping and climping circuits. Analyze inverting amplifier, non-inverting amplifier, summing amplifier and multistage of op-amp circuits.
Part 1A :Fundamental of basic electrical instrument.
Theory :The oscilloscope, often just called the scope, displays the signals as a plot of magnitude versus time. It is an electronic test instrument that displays electrical signals graphically, usually as a voltage (vertical or Y axis) versus time (horizontal or X axis) as shown in figure 1. The intensity or brightness of a waveform is sometimes considered the Z axis. There are some applications where other vertical axes such as current may be used, and other horizontal axes such as frequency or another voltage may be used.. A signal or function generator is used to produce periodic signals of the frequency, amplitude, and waveform needed for input to the device under test. The counter/timer can measure time intervals and frequencies very accurately, and the digital multimeter measure voltages, currents, resistance, and it can test silicon diodes and transistors. Everything you do in an electronics laboratory depends upon your familiarity with these instruments.
Equipments :1-oscilloscop.
2-function generator.
3-probe.
4-resistors(1kohm,5kohm).
5-wire/jumper.
Procedures: First of all, all the switches
