    1345 Words  | 6 Pages

    What is electromagnetism? Merriam-Webster states that “electromagnetism is magnetism developed by a current of electricity.” An alternative definition suggests that electromagnetism is a fundamental physical force that is responsible for interactions between charged particles which occur because of their charge. To fully understand how electromagnetism affects us, it is important to understand the basic foundation of electromagnetism. The field of electromagnetism was only six years old when Henry

    ¬¬¬¬¬¬Abstract Electrical circuits are described with mathematical expressions. Usually, it is possible to calculate the currents and voltages in a circuit by solving a set of equations, the calculations are required to design a safe circuit.and this is one reason why advanced mathematics is so important in the field of electrical engineering. The circuit equations can be determined using Ohm’s Law, which gives the relationship between voltage and current in a resistor (V=IR), and Kirchhoff’s Current

    In addition to the discovery of latent heat being used for calorimetry, latent heat also brought about changes to the steam engine. As previously mentioned, Joseph Black worked closely to James Watt, inventor of the steam engine, doing several experiments together; their teamwork is what truly what gave rise to the discovery of latent heat. So although Joseph Black did not directly invent the steam engine, his discoveries in the lab is what made the industrial invention possible (Cooper, 1999). A

    Capacitors are two conducting plates separated by an insulating material. So when a voltage is applied across the plates, the battery works on the plate to separate the negative and positive charges on the capacitor. In lab 21 we will observe this type of charge in snap circuits by using the snap circuit kit from our lab and a stopwatch. In part two of this lab, I observed how the relationship how current, voltage and resistance are used to through a system in regards to Ohm’s Law. Introduction

    Today communication is simpler than it was many years ago. We can call and text anyone in the world with just a tap of our finger. Over a hundred years ago people had to handwrite letters and send them in the mail. This changed thanks to Samuel F.B. Morse. He simplified the telegraph machine and invented the Morse Code.(pbs.org). Samuel Morse was an influential person whom helped the world communicate easier and become more innovative. When Samuel Morse first went to Yale University his interest

    Does the type of battery used to create a motor affect the time the motor spins? If the type of battery affects the amount of time the coil spins then the D-battery powered electric motor will spin for the longest period of time. The procedures were to create the motor and find a spot for the motor to spin. You also needed to keep track of the time the motor spinned. When the motor stops spinning record the time on a data table. The independent variable was the type of battery used for the motor

    Pietro Russolo Science Y10 John Charters 6/11/15 Alessandro Volta Alessandro Volta, born on February 18th, 1875 in Como, Lombardia, Italy, was a physicist and chemist. He was known for creating the first electric battery, which in the 1800s was referred to as the “voltaic pile”, though now known as a “cell” in scientific terms. Alessandro Volta did not initially set out to create a battery, but carried out experiments in order to prove that another Italian scientist, Luigi Galvani’s theory of

  • How Did Benjamin Franklin Discover Electricity In The 1600's

    369 Words  | 2 Pages

    Before the 1600’s, electricity was not a huge concept. The idea of electricity or the need for it was very foreign to several people. Until one day, in the 1700’s, when a man of the name Benjamin Franklin introduced this idea and made it into a reality with his invention of the Electrostatic Machine. The Electrostatic Machine laid the groundwork for understanding electricity and magnetism in depth. In the 1600’s, philosophers, scientists, and instrument makers created many devices to generate

    A magnet is a material or object that produces a magnetic field. It is a force that pulls on other ferromagnetic materials, such as iron, and attracts or repels other magnets. A permanent magnet is an object made from a material that is magnetized and creates its own persistent magnetic field. Materials that can be magnetized, which are also the ones that are strongly attracted to a magnet, are called ferromagnetic (or ferrimagnetic). These include iron, nickel, cobalt, some alloys of rare earth
