Lab 3. Dc circuits and Ohm’s law of measurments Helina Wolfe Tannaz Farnoudi and Najah Rouse Physics 246-205 Professor Joe Renaud 09/23/13 Word count:1453 Abstract: The aim of this experiment was to understand the relationship between the variables of Ohm’s law and how they are part of an operation of an electric circuit. Introduction: This experiment was done in two parts. The first part consisted of understanding how to determine the current‚ voltage and resistance

Projectile Motion Purpose: An object in a projectile motion move horizontally with no acceleration and vertically with the gravitational acceleration at the same time. This experiment is to investigate projectile motion using experiments‚ equations and comparing the expected and experimental data. Procedure: Case I: Use formulas to find equation of horizontal Range (R) in a projectile motion. Rearrange equation for Rmax‚ and find the angle Adjust the launches angle to angle Launch

Israel RECEIVED JANUARY 16‚ 2004; REVISED JULY 21‚ 2004; ACCEPTED OCTOBER 28‚ 2004 Keywords acid value vegetable oils indirect titration A new method of acid value determination in vegetable oils has been developed. The method is based on (a) simple‚ rapid and complete extraction of acids from an oil test portion into reagent (0.05 mol dm–3 triethanolamine (B) in the mixture of 50 % H2O + 50 % 2-PrOH) and (b) indirect titration of acids in BH+ form against aqueous alkali in the presence of a

Impulse and Momentum Lab Part I: As the first lab of the Physics 2 curriculum‚ our class completed a lab experiment that introduced us students to a new concept that would be a foundation to the future topics that we learn in this class. In this lab activity‚ we used a lab cart on a flat track to compare the collision of the cart with a force sensor with and without the plunger during different trials. The materials that we would need for this activity are a lab cart on a flat track‚ a timer

Hybrid Electric Vehicles (HEV) usually need power conditioning‚ typically rectification which uses non linear devices‚ that produces a non-sinusoidal line current due to their non- linear input characteristics. The reduction of line current harmonics for enhancing the efficiency is Power Factor Correction. For active power factor topologies‚ there exist bridged and bridgeless power converter circuits. This paper focuses on a bridgeless Interleaved Boost Converter (IBC) for shaping the line
