needed are as follows: capacitors of values 0.33 uF and 0.47uF‚ resistors of values 56k‚ 5.6k‚ 680 and 6.8k‚ a 2N3904 NPN transistor. Equipment needed for measuring the input and the output signals are a function generator‚ an oscilloscope‚ multimeter and a +15V DC power supply. However‚ because this experiment is a simulation activity‚ Multisim simulator was used to conduct the experiment. B. Procedure To construct the amplifier circuit shown in fig. 1‚ connect the 56k and 5.6k resistors

Efficient Propeller Design | AbstractHow does a helicopter generate enough lift to fly? How does a speedboat get moving fast enough to pull someone on water skis? Here ’s a project on designing propellers to do the job. ObjectiveThe goal of this project is to investigate how changes in chord length affect the efficiency of propellers.IntroductionA propeller‚ like an airplane wing‚ is an airfoil: a curved surface that can generate lift when air moves over it. When air moves over the surface of

Chelsea Samatra‚ Kenneth Ragus Samatra‚Ragus 1 Ms. Daligcon Period 4 A Battery That Makes Cents Abstract Many coins in the pile will make the most electricity. If there are more coins in the pile‚ then the more electricity it can produce‚ because the more electrons you have‚ the more electricity you will get. Batteries are expensive‚ but you can make one for exactly 24 cents! In this experiment‚ you will make your own voltaic pile using
