CAPACITOR CIRCUITS

1. Definition
  A circuit is any path along which electrons can flow. There are two types of circuits, one is the series circuit and the other is the parallel circuit.
   When a capacitor is connected to a battery in a circuit, the electrons flow from the battery to the capacitor plate that is connected to the battery's negative terminal. The capacitor plate that is connected to the positive battery terminal does the opposite, it sends electrons back to the battery.

   The battery could produce a continuous flow of current, which made it possible for the development of the first electrical circuits. Alessandro Volta invented the first battery, the voltaic pile in 1800. The very first circuits used a battery and electrodes immersed in a container of water. Volta discovered he could produce a steady flow of electricity using bowls of salt solution that were connected by metal strips. The first practical use of the circuit was in electrolysis, which is a process where electric current passed through a substance induces a chemical change. This led to the discovery of several new chemical elements.


4. Uses in Everyday Life
   Electric circuits can be seen in all electrical appliances around us. Series circuits can be seen in a string of Christmas lights, if one of the bulbs is missing or burned out, no current will flow and none of the lights will go on. The wiring system used in a house is an example of parallel circuit, a single electric power source supplies all the lights and appliances with the same voltage. If one of the lights burns out, current can still flow through the rest of the lights and appliances, if there is a short circuit however, the voltage drops almost to zero and the entire system goes down.

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

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'
