DE LA SALLE UNIVERSITY DASMARINAS Dasmarinas City‚ Cavite OBSERVING THE ELECTRICAL ACTIVITY OF THE HEART USING ELECTROCARDIOGRAM Villar‚ Samantha Belle B. Ylade‚ Kristianne Joy G. Perillo‚ Jeanne 18 March 2014 ABSTRACT In this activity‚ the electrical activity of the heart was examined using the Electrocardiogram (ECG/EKG). Proper handling was performed by removing the metals present in the body and by cleaning the surfaces of the skin‚ to avoid the disruption of signal of the machine. Assessment

Kevin Williams Project 1 The use of electricity and magnetism in transportation When Benjamin Franklin discovered electricity‚ it was probably one of the biggest discoveries known to mankind. Even though our dependence of electricity is a lot‚ however at the same time it’s easy to forget how dependent we actually are on it. Electricity always has and always will play a huge part in our everyday life. It’s hard to imagine humanity without it. When it comes to transportation‚ it is going to rewrite

Aircraft Systems and the Importance of Pilot Training The operation and maintaining of an aircraft comes with many responsibilities and obligations. This is especially true when running a scheduled airline operating under 14 C.F.R. Part 121. When under these rules‚ profit margins can be very thin and a manager must be able to lead the airline through some very difficult economic circumstances. Many of these operating procedures can be streamlined through proper pilot training and proper utilization

Physical Science Review Waves‚ Sound and Light Waves- What are Waves? 1. 1 .The substance that a move through is called a medium. 2. True or False: Particles are squeezed together during rarefactions. 3. True or False: Waves that require a medium through which to travel are called electromagnetic waves. 4. True or False: The matter in the medium moves perpendicular to a transverse wave. 5. What medium is often used to transfer computer information? Optic Fibers 6. 6 .A

Ampere’s Law Jessica Warfield Partner: Rachel Beckner TA: Joel Mazer March 15‚ 2012 Conclusion: This experiment clearly demonstrated how Ampere’s Law relates the magnetic field to the current using the relationships stated in the formula B= μ0I2πr. This relationship allowed to the experiment to calculate the value of permeability of free space in order to verify the relationship that is outlined in Ampere’s Law. This lab also allowed us to measure magnetic field strength as a function of

Electricity is a form of energy. Electricity is the flow of electrons. All matter is made up of atoms‚ and an atom has a center‚ called a nucleus. The nucleus contains positively charged particles called protons and uncharged particles called neutrons. The nucleus of an atom is surrounded by negatively charged particles called electrons. The negative charge of an electron is equal to the positive charge of a proton‚ and the number of electrons in an atom is usually equal to the number of protons

ESO210/ESO203A: Introduction to Electrical Engineering Assignment 4 Date of Submission: 20th March‚ 2013 1. The rotor shown in Fig.1 has two coils. The rotor is nonmagnetic and and is placed in a uniform magnetic field of magnitude B0 . The coil sides are of radius R and are uniformly spaced around the rotor surface. The first coil carrying a current I1 and second coil carrying a current I2 . Assuming that the rotor is 0.30 m long‚ R=0.13 m‚ and B0 = 0.85 T‚ find the Θ directed torque as a

My research is to determine if electricity moves better through thick wires or through thin wires. For this experiment I used two size D batteries‚ two flashlight bulbs‚ one 6.5 inch thin steel wool piece‚ one 6.5 inch thick steel wool piece‚ two 2 inch pieces of straw‚ and some electrical tape. Steel wool is a material made from thin fibers of steel made into a pad. (http://www.wisegeek.com/l-what-is-steel-wool.htm) There are many uses for steel wool. It can be used for sanding furniture‚ removing
