OBJECTIVES To demonstrate the effects that a bypass capacitor has on amplifier voltage gain (Av). To demonstrate the ac operation of the common-emitter (CE) amplifier. INTRODUCTION A common emitter amplifier is one of three basic single-stage bipolar-junction-transistor (BJT) amplifier topologies‚ typically used as a voltage amplifier. In this circuit the base terminal of the transistor serves as the input‚ the collector is the output‚ and the emitter is common to both. The input signal to a

Theme: Crisis and Opportunity Topic: Water Crisis- a catalyst of Innovation and International Cooperation 1) Introduction Nowadays‚ we have created our own world of technology. Convenience and efficiency are catered through it. Yet‚ the earth‚ the natural world‚ seems to rebel against such artificial world‚ by sending signals of natural crises to us. In this project‚ we are going to talk about "How people benefit from Water Crisis" surrounding the theme "Crisis and Opportunity". The water

AIMS At the end of the experiment‚ students should be able to synthesise pure aspirin using chemical tests such as esterification and recrystallization independently and to also find out the melting point range of aspirin using melting point determination. INTRODUCTION Aspirin‚ which is also known as acetylsalicylic acid‚ is one of the commonly used and widely found in any drugstore or pharmacy. Its properties make aspirin a well-rounded drug that reduces inflammation and fever and also relieves

The members in our group were Whitney‚ myself‚ and Charlotte. The title of this lab was “reaction types.” The purpose of this lab was to identify the reaction type‚ balance equations‚ and observe the reactions .Our hypothesis was if there was many stations with fire‚ then they’re would be many combustion reactions. The procedure of the first lab was to place a solid piece of magnesium metal in the bottom of the smallest tube. Place this test tube in the test tube holder. Using tongs pick up the

Practical 1: Observation of mitosis in garlic root tips Introduction The practical will involve the preparation‚ observation‚ and classification‚ of the various stages of mitosis by observing garlic root tips using a microscope. The study comes under the heading of cytogenetics which is the visual characterisation of genetic material and the study of how that material reacts during the life of the cell. Strictly speaking‚ mitosis is the division of the nucleus into two daughter nuclei that are

Trial # Guess Observation Explanation Trial 1 The dyed red water will not seep into the blue cold water. My guess was indeed correct and red water did not interfere with the blue water. Because the molecules in the blue water are much closer together because its cold and well the red water has warm/hot water and the molecules are everywhere. The molecules in the blue water are so dense that they’re making a layer so that the molecules from the red jar do not come through. Trial 2 I think

(1) Answer to Question in lab manual. NO introduction/background etc. 1. What is the retention time for caffeine? Retention time for caffeine : 4.149+4.142+4.152+4.1454 = 4.15 2. What is the retention time for benzoic acid? Retention time for caffeine : 2.651+2.817+2.857+2.9274 = 2.81 3. How are the retention times for caffeine and benzoic acid related to their chemical structure and the nature of the chromatographic

Discussion: Conclusions: • For both meters it was noted from plots that the difference in pressures are directly related to the rate of discharge. • Coefficient of discharge have a varying value depending on the rate of discharge‚ where in the Venturi meter the value of Cd increase gradually at first with increasing the rate of discharge till a point approaching one‚ then started to descend with further increment in the rate of discharge. • The Coefficient of discharge " Cd
