ohms law

In most metallic conductor, current flows relationships with potential governed by Ohm's Law. Ohm using a series of simple experiments as shown below Ohm experiment. He (Ohm) using a series of potential sources in series, measuring the amount of current that flows and found a simple linear relationship and is known as Ohm's law. Ohm's law is a statement that the electric current flowing through a conductor is always proportional to the potential difference given to the conductor. A conductive object (conductor) is said to obey Ohm's law if the resistance value is not dependent on the polarity of the potential difference and given to the conductor. Although this statement is not always true for all types of conductors, however, the term "law" still used by historical reasons. Mathematically dapalam Ohm's Law can be expressed mathematically as the following equation. Where: V = voltage present at both ends of the conductor in units of volts I = electric current flowing in a conductor in amperes R = the value of the electrical resistance (resistance) contained in a conductor in units of ohms where R = V / I is called the resistance of the load. The name is very appropriate because R be a measure of how much the conductor put a halt to the flow of electrons. The series of experiments Experiment Ohm's Law ohm's law above is an electrical circuit that can be used to prove theorems or legal ohm. This law is found or coined by George Simon Ohm, a German physicist in 1825 and published in a paper entitled The Galvanic Circuit Investigated Mathematically in 1827. Ohm's law is limited to certain conditions, even the law does not apply if the temperature of the conductor is changed. For material - material or electronic devices such as diodes and transistors, the relationship I and V are not linear.
