Capacitor Charge and Discharge Laboratory: Types of Capacitors and Circuit Calculations - , Lab Reports of Electrical Circuit Analysis

A laboratory report for a circuit analysis ii course at georgia southern university, focusing on capacitor charge and discharge. Students are required to write about three different capacitor types - film capacitors (polyethylene and polycarbonate), ceramic capacitors, and electrolytic capacitors - including their main characteristics, polarization, construction, materials, capacitances, and voltage ranges. The report also includes calculations for time constants in rc series circuits with three different capacitors and the plotting of voltage and current waveforms for capacitor charging and discharging using matlab or excel.

Circuit Analysis II Laboratory TEET 3145 Laboratory # 3 Capacitor Charge and Discharge Fall 2009 Georgia Southern University  Mechanical and Electrical Engineering Technology      Page 1 of 2  Name:________________________ Pre-laboratory Work Part 1. Finding out about capacitor types. For this part you are asked to write three brief paragraphs, one for each type of capacitor ( total  about 300 words).  It is preferable to type it, if not, use a neat and readable handwriting.    Search in books or internet about the different capacitor types. In particular find out the main  characteristics of:    • Film capacitors (polyethylene and polycarbonate)  • Ceramic capacitors   • Electrolytic capacitors    Indicate which ones are polarized and which ones non‐polarized. Also explain briefly its basic  construction and materials used. Investigate what are the ranges of capacitances and the range of  voltages. Cite your sources of information, use at least two.  Please use a formal format for citing  references in academic writing. Examples can be found at:  http://www.liu.edu/cwis/cwp/library/workshop/citchi.htm  Part 2. Calculations 1. Time constant.  Calculate the time constant for a RC series circuit. Consider  R = 330 kΩ, and  consider three different capacitors:  1000 μF, 100 μF, and 1μF. Indicate the units.    Table 1 Values for R and C    Time Constant  R = 330 kΩ,  C= 1000 μF      R = 330 kΩ,  C= 100 μF      R = 330 kΩ,  C= 1 μF        2. Waveforms for the charge of a capacitor. Use Matlab  or Excel to plot the voltage and  current waveforms for the charge of a capacitor.  Consider:  C = 100μF and  R = 330 kΩ.   Assume the capacitor is initially discharged and at  t = 0   a  12 volts power supply is  connected to the circuit  (see fig 1).  Use one plot for the current waveforms and another  plot for the voltage waveforms.
