The ohm (Ω) is the standard unit of electrical resistance in the International System of Units (SI). It quantifies how much a material opposes the flow of electric current. One ohm is defined as the resistance that allows one ampere of current to flow when a voltage of one volt is applied across it. This fundamental unit plays a crucial role in electrical engineering, physics, and various applications in everyday life.
The ohm is standardized based on the physical properties of materials and is defined by the relationship between voltage, current, and resistance as described by Ohm's Law. This law states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R). The formula is expressed as: [ V = I \times R ]
The term "ohm" is named after the German physicist Georg Simon Ohm, who formulated Ohm's Law in the 1820s. His work laid the foundation for the field of electrical engineering. Over the years, the definition of the ohm has evolved with advancements in technology and measurement techniques, leading to the precise standards we use today.
To illustrate the concept of ohms, consider a circuit with a voltage of 12 volts and a current of 3 amperes. Using Ohm's Law: [ R = \frac{V}{I} = \frac{12V}{3A} = 4Ω ] This means the circuit has a resistance of 4 ohms.
Ohms are widely used in various applications, including electrical circuits, electronics, and telecommunications. Understanding resistance is essential for designing circuits, troubleshooting electrical issues, and ensuring safety in electrical systems.

The siemens (symbol: S) is the SI unit of electrical conductance, named after the German engineer Ernst Werner von Siemens. It quantifies how easily an electric current can flow through a conductor. The higher the siemens value, the greater the conductance, indicating a lower resistance to the flow of electric current.
The siemens is part of the International System of Units (SI) and is defined as the reciprocal of the ohm (Ω), the unit of electrical resistance. This standardization allows for consistent measurements across various applications in electrical engineering and physics.
The concept of electrical conductance was developed in the 19th century, with Ernst Siemens being a pivotal figure in its establishment. The siemens unit was officially adopted in 1881 and has since evolved to become a fundamental unit in electrical engineering, reflecting advancements in technology and understanding of electrical phenomena.
To illustrate the use of siemens, consider a circuit where a resistor has a resistance of 5 ohms. The conductance (G) can be calculated as follows:
[ G = \frac{1}{R} = \frac{1}{5 , \Omega} = 0.2 , S ]
This means that the resistor has a conductance of 0.2 siemens, indicating that it allows a certain amount of current to pass through it.
Siemens is widely used in various fields, including electrical engineering, telecommunications, and physics. It is essential for calculating the conductance of materials, designing circuits, and analyzing electrical systems.
