Ohm's Law is a simple formula for calculating the voltage drop across a resistor or other component. This formula can be used to calculate the voltage drop across any component of an electric circuit. Ohm's law is also used in DC ammeter and other DC shunts to divert the current.
Ohm's Law is an important law of physics that states that the voltage or potential difference between two points can be calculated using current, resistance and time. Ohm's Law was the first law of electrical resistance and it is also known as Ohm's law. It is a very important and widely used law in electronic circuits and in electricity, particularly in semiconductors.
The unit for resistance is the ohm, a basic unit of measurement for electrical current. The symbol Ω has many uses in science and engineering. In this article we will briefly discuss some applications of the symbol Ω in physics and physics education.
Rearranging I = V/R gives R = V/I
The units of resistance are 1 ohm = 1 volt per ampere: 1Ω=1VA 1 Ω = 1 V A .
