Ohm's law for resistance
Ohm's law states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points, given that the temperature and other physical conditions remain constant. Mathematically, Ohm's law is expressed as:
V = I * R
V: represents the voltage across the two points in volts (V).
I: denotes the current flowing through the conductor in amperes (A).
R: is the resistance of the conductor in ohms (Ω).
According to Ohm's law, the resistance (R) of a conductor is the ratio of the voltage (V) across it to the current (I) flowing through it. In other words:
R = V / I
This relationship implies that the resistance of a conductor remains constant as long as the physical conditions, such as temperature and material properties, remain unchanged. Ohm's law is fundamental in understanding and analyzing electrical circuits and is a cornerstone principle in the field of electrical engineering.
