OHM LAW 2.KIRCHOFF 1 LAW 3.KIRCHOFF 2 LAW Electrical circuits • Electric Circuit is a path that is passed by an electric current • electrical circuit is divided in two namely • Ohm's Law Ohm's Law Understanding Ohm's Law is a theory that discusses the relationship between Voltage (Volt), Current (Ampere), and electrical resistance in a circuit (Ohm). 1 Ohm is an electrical resistance which causes a difference of one volt when a current as 1 Ampere flows. Ohm's Law Sound: "The strong electric current at an electrical load is directly proportional to the voltage and inversely proportional to the resistance". Ohm's Law Formula: The symbol of resistance is R, the symbol of current is I, and the symbol of voltage is V. Based on Ohm's law above, the following formula can be taken; • Information: • I = The amount of current flowing at the conductor => with Volt units • V = the voltage at the conductor => with units of Volt • R = Large resistance => Ohm units Based • on the benchmark formula above, we can find the values of I, V, and R in an electrical circuit. To find R, you can simply use logic based on the formula above KIRCHOFF'S LAWS 1 AND 2 • In electrical equipment, we usually encounter branched electrical circuits. To calculate the amount of electric current flowing at each branch produced by an electric current source. • Gustav Kirchhoff (1824-1887) put forward two legal rules that can be used to help these calculations. Kirchoff's Law 1 is called the branch point law and Kirchhoff's Law 2 is called the loop law. KIRCHOFF'S LAW 1 • In the mid-19th century Gustav Robert Kirchoff (1824 - 1887) discovered a way to determine the electric current in a branched circuit which was then known as Kirchoff's Law. • Sound of Kirchoff Law 1: "The amount of strong current entering a branching point is the same as the amount of strong current coming out of the branching point". KIRCHOFF'S LAW FORMULA 1: • The sound of Kirchoff's law 1 above, which was later known as Kirchoff's law I. Mathematically stated: • If it is depicted in the form of a branched circuit it will be obtained as follows: Kirchoff's Law 2 Kirchoff's law as a whole is 2, after the above explained about his 1st law. Kirchoff's Law 2 is used to determine the strength of the current flowing in a branched circuit in a closed state (a switch in a closed state). Sound of Kirchoff's Law 2: "In a closed circuit, the number of GGL (E) algebra and the number of potential decreases is zero". The meaning of the amount of potential reduction equal to zero is that no electrical energy is lost in the circuit, or in the sense that all electrical energy can be used or absorbed.
