Ohms law
States that, for a given resistance, the potential difference in an electric current is directly proportional to the current intensity.
V= IR V= potential difference (in V)
R= resistance (in Ω)
I = Current Intensity (in A)
is the ability of a material to hinder the flow of electric current.
Ohm's law states that the voltage (V) across a conductor is directly proportional to the current (I) flowing through it, with the constant of proportionality being the resistance (R) of the conductor. This relationship can be expressed mathematically as V = IR.
To understand this law better, let's break it down. Voltage is the measure of electrical potential difference between two points in a circuit. It is measured in volts (V). Current, on the other hand, is the flow of electric charge through a circuit and is measured in amperes (A). Resistance is the measure of how much a material opposes the flow of electric current and is measured in ohms (Ω).
So, Ohm's law tells us that if we increase the voltage across a conductor, the current flowing through it will also increase proportionally, as long as the resistance of the conductor remains constant. Similarly, if we increase the resistance of the conductor, the current flowing through it will decrease proportionally, as long as the voltage remains constant.
This law is fundamental to understanding how electrical circuits work and is used extensively in electrical engineering and physics. It allows us to calculate the amount of current flowing through a circuit given the voltage and resistance, or to calculate the resistance of a conductor given the voltage and current.
In summary, V = IR is a simple yet powerful formula that describes the relationship between voltage, current, and resistance in a conductor. It is a fundamental concept in electrical engineering and is used to design and analyze circuits of all kinds.
