A. ENG237-02: Transients in RC and RL Circuits 0. Introduction The objective of this experiment is to study the DC transient behaviors of RC and RL circuits. This experiment has divided into 6 parts: 1. Charging curve from measured data ( R = 10M Ω and C = 4 mF ) 2. Draw the charging curve by the graphical method 3. Discharging curve from measured data ( R = 5M Ω and C = 4 mF ) 4. Draw the discharging curve by the graphical method 5. Display of the charging and discharging

Introduction! ! The Michelson Interferometer is commonly used to determine the wavelength of light or measure very small distances. It was invented by Albert Abraham Michelson and is commonly used in optical interferometry‚ a branch of physics involving a family of techniques one could use to extract information about waves by superimposing them. ! ! The original application of the Michelson Interferometer was to the famous Michelson-Morley experiment in 1887. Prior to Einstein’s

Introduction In unit 7.3 the experiment tested the ability of lactase to specifically bind and interact with lactose compared to maltose. In unit 7.4 the experiment tested the role‚ if any‚ that metal ions have on the activity of lactase. My hypothesis for unit 7.3 was knowing that lactase is specific for lactose‚ lactose will separate into galactose and glucose‚ as maltose will not change (153-155). Lactase should like lactose. For unit 7.4 my hypothesis was that EDTA will remove the ions‚ and

Our main goal was to test organisms’ resistance and susceptibility to bacteria‚ and whether the cell wall of bacteria exposed the membrane to pathogen or protect it from pathogens. I thought P. aeruginosa was gram-positive and therefore it would be susceptible. That was my hypothesis.We divided antiseptic agar plate into quadrants and divided antibiotics agar plate into six areas. We wrote the organisms’ name‚ date‚ and the temperature on the bottom of the agar plates. For antiseptic‚ our group used

not exist (Lab Manual 3 pg. 1). They help in many different ways that are useful to the body of living organisms. Enzyme are used to speed up chemical reactions (Lab Manual 3 pg. 1). Through this process‚ they are considered very unique because they are not altered or consumed within the reaction (Lab Manual 3 pg. 1). This is why enzymes are considered biological catalysts. They also do not alter the equilibrium of a chemical reaction nor the amount of free energy that is released (Lab Manual 3 pg

bacteria. Learning how to gram stain‚ use specific media such as MacConkey agar‚ and test antibiotics to see which antibiotic would react best against a specific organism. All these techniques helped me prepare for the final lab‚ identification of an unknown bacterium. For the final lab‚ I received the organism “6A”. To start identifying this organism‚ I did a gram-stain to identify if the organism is gram positive or negative. I created two slides to ensure that I did the stain correctly with similar

It is an intensive property‚ which means the amount of material tested is irrelevant. This lab will determine the melting point temperatures of two known pure substances‚ naphthalene and p-dichlorobenzene‚ using micro-sized quantities and a capillary
