Description

Electricity and magnetism are separate yet interconnected phenomena associated with electromagnetic force. Together, they form the basis for electromagnetism, a key physics discipline. In an electromagnetic wave, the electric field and magnetic field are perpendicular to one another. Except for behavior due to the force of gravity, nearly every occurrence in daily life stems from the electromagnetic force. It is responsible for the interactions between atoms and the flow between matter and energy. Other fundamental forces govern radioactive decay and the formation of atomic nuclei. This course begins by introducing you to the basics of understanding electrostatics. The Coulomb's law equation provides an accurate description of the force between two objects whenever the objects act as point charges. Coulomb's Law has many applications to modern life, from Xerox machines to laser printers, and to powder coating. This course analyzes Coulomb's law in vector form as well as the comparison of electrostatic and gravitational forces
The course then introduces you to the different types of materials. Have you ever experienced a feeling of electric shock while coming in contact with a household appliance? or while trying to plug your phone to charge? Well, was it a scary experience? But, why does that happen? Also, why don’t we get a similar experience when we are in contact with wooden materials? By the end of this course, you will be able to differentiate between the two types of materials with the aid of examples. You may wonder how charges can continuously flow in a uniform direction through wires. In order for the Source-and-Destination scheme to work, both need to have an infinite capacity for charges in order to sustain a continuous flow. This is possible with the aid of circuits; a never-ending looped pathway for charge carriers.

Lastly, you will learn about the relationship between current and resistance which is expressed by Ohm’s Law. This states that the current flowing in a circuit is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit, provided the temperature remains constant. In 1845, a German physicist, Gustav Kirchhoff developed a pair or set of rules or laws which deal with the conservation of current and energy within electrical circuits. These two rules are commonly known as Kirchhoff's Circuit Laws with one of them dealing with the current flowing around a closed circuit, Kirchhoff's Current Law. While the other law deals with the voltage sources present in a closed circuit, Kirchhoff's Voltage Law. Magnetism is caused by the motion of electric charges. This course outlines the magnetic lines of force, its properties, and the magnetic forces between permanent magnets. So, register for this course today and begin your next learning journey!
