ELECTRIC CURRENT

1. Definition
   When electrons move, we say that an electric current is produced. An electric current is formed by moving electrons. Conventional current is in the direction opposite to electron flow. An electric current (I) is the rate of flow of electric charge (Q).

2. Formula

Where:
  • I stands electric current (A)
  • Q stands for electric charge (C)
  • t stands for the time taken (s) 
3. Important Figure
   Nikola Tesla (1856-1943) was a Serbian-American engineer and physicist who invented the first alternating current (AC) motor and developed AC generation and transmission technology. Though he was famous and respected, he was never able to translate his copious inventions into long-term financial success, unlike his early employer and chief rival, Thomas Edison. In the 1890s Tesla invented electric oscillators, meters, improved lights, and the high-voltage transformer known as the Tesla coil.

4. Uses in Everyday Life
   Electric current can be seen from any electrical appliances that you see in everyday life, they're used to power devices and even some of the methods of transportation that we see all around us. To make things operate, electrical energy must be emitted from energy sources such as power plants, to enable an object to consume the power it needs to function.

RESISTANCE AND RESISTIVITY

Image
1. Definition    The resistance of a component is a measure of the opposition an electric current experiences when it flows through the component. The resistance (R) of a component is the ration of the potential difference (V) across it to the current (I) flowing through it.    Aside from temperature, the resistance (R) of a conductor also depends on: Its length Its cross-sectional area (A) or thickness The type of material it is made of 2. Formula Resistance Formula Where: I stands for electric current (A) V stands for the potential difference (Volt) R stands for resistance (Ω) Resistivity Formula Where: R stands for resistance (Ω) ρ stands for resistivity (Ωm) A stands for cross sectional area (m²) L stands for length (m) 3. Important Figure    Georg Ohm (1789-1854) was a German physicist, he is best known for his "Ohm's Law" which states that the current flow through a conductor is directly proportional to the p

ELECTRIC POTENTIAL

Image
1. Definition    Electric potential is the magnitude of the electric potential energy for each charge. 2. Formula     Where: V is the electric potential (Volt) k is a constant with a value of  8.99 x 10 9 N m 2 /C 2   q is the charge of each object (C) r is the distance between the charges (m) 3. Important Figure        Alessandro Volta was a physicist, chemist, and a pioneer of electrical science. He is most famous for his invention of the electric battery. He discovered that electric potential in a capacitor is directly proportional to electric charge and in recognition of Volta's contribution to science, the unit of electric potential is called the volt. 4. Uses in Everyday Life    A battery powered electric circuit has locations of high and low potential. A charge moving through the circuit will experience charges in electric potential as it moves locations. In a battery there is an electric field established between the two termina

KIRCHOFF'S LAW

Image
1. Definition    Kirchhoff's laws quantify how current flows through a circuit and how voltage varies around a loop in a circuit. Kirchhoff's 1st law states that current flowing into a node (or a junction) must be equal to    current flowing out of it. This is a consequence of charge conservation. Kirchhoff's 2nd law states that the sum of all voltages around any closed loop in a circuit must equal zero. This is a consequence of charge conservation and also conservation of energy. 2. Formula Where: I stands for the electric current (A) Where: V stands for voltage (Volt) I stands for electric current (A) 3. Important Figure    Gustav Kirchhoff was a famous German physicist born in 1824. Gustav Kirchhoff studied mathematical physics at Albertus University of Konigsberg, graduating in 1847. In 1845, Kirchhoff extended Ohm's work by developing a method to understand and predict the behavior of much more complex circuits. Kirchhoff'
