Objectives The objective of this lab is to create an RC circuit that has a time constant of 10. 2. Method and Principle: The RC circuit that we created on the breadboard was a series circuit. RC circuits contain resistors and capacitors, and are connected to a voltage source. In our case, this voltage source was the battery. When we were measuring the voltage on the computer, we used a switch insteadRead MoreThe Impact Of Eigenvalues On The Electron Phonon Coupling Strength Of Indium And Its Binary Alloys841 Words   |  4 PagesIMPACT OF EIGENVALUES ON THE ELECTRON-PHONON COUPLING STRENGTH OF INDIUM AND ITS BINARY ALLOYS S. K. Chakrabarti Department of Physics Tribhuvan University, MMAM Campus, Biratnagar, Nepal ABSTRACT Indium is a trivalent metal. Though chemically not so reactive, it often forms complexes within its binary alloys. In this theoretical work we have studied the impact of eigenvalues on the electron-phonon coupling strength of indium. We have also dealt with the same for two binary alloys of it vizRead MoreLab Report On Rc Time Constant906 Words   |  4 PagesLab Report 4 RC Time Constant Physics 262-003 Author: A.

Coughran 4/5/17 Objective: The objective in Lab 4 is to measure the RC time constant for a capacitor in a series RC circuit with a resistor. This will be accomplished by the analysis of voltage curves across the resistor. Theory: Kirchoff’s Voltage Law states that the voltage sum across a series circuit containing one resistor and a capacitorRead MoreNewton’s Laws of Motion in Modern Aircrafts1087 Words   |  5 Pagesvia airplanes became easier and more efficient with the replacement of jet engines in July 16, 1949, by the famous inventor Frank Whittle (FindtheData, n.d.). The principles behind how a jet-engine powered aircraft works associate with many laws of physics, from Newton’s Law of Inertia to the Third Law of Motion. These laws are also applicable to the aerofoil and the engines aerodynamically, in particular with the four forces: lift, drag, weight and thrust which allows an aircraft to maneuver acrossRead MoreI had a dream that I could fly.

It was an embarrassed moment, and I didn’t realize that that w as a moment leading me to success. It gave me a chance to keep trying. Working with my dad’s friend who is a hot fan of RC plane, playing â€Å"Real Flight†, a simulator, to get a sense of real flying, I started to know more about plane while I found more unknown to me. In TU Delft, in the Aerospace Engineering Department (AED), I will be able to overcome the embarrassment andRead MoreEssay physics lab ohms law832 Words   |  4 Pagesresistance and current we can set the equation for resistance to be; R = where the unit is called Ohm (â„ ¦). â€Å"The current through a resistor is directly proportional to the applied voltage V and inversely proportional to the resistance† (College Physics Laboratory Experiments, 43) in our lab experiment we used some machinery to produce and to measure voltage and some current.

Now, in such a society we suppose that two individuals living close together combine their wealth and build a facility to race their remote controlled (RC) cars right next to their houses, because they are RC fanatics and would get enjoyment out of this center. Attracted by the facility, many people get into the RC hobby and want to use the facility that was built. Since, the first two individuals spend their own wealth building this facility, they decide to charge other people for
