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.

Mho (℧) is the unit of electrical conductance, representing the reciprocal of resistance measured in ohms (Ω). It is a crucial metric in electrical engineering and physics, indicating how easily electric current can flow through a conductor. The term "mho" is derived from the word "ohm" spelled backward, symbolizing its inverse relationship with resistance.
Mho is part of the International System of Units (SI), where it is officially recognized as siemens (S). One mho is equivalent to one siemens, and both units are used interchangeably in various applications. The standardization of mho ensures consistency in electrical measurements across different fields and industries.
The concept of electrical conductance has evolved significantly since the early studies of electricity. The term "mho" was first introduced in the late 19th century as electrical engineering began to take shape. As technology advanced, the need for precise measurements in electrical conductance led to the adoption of the siemens as the standard unit, but the term "mho" remains widely used in educational contexts and practical applications.
To illustrate the use of mho, consider a circuit where the resistance is 5 ohms. The conductance (in mho) can be calculated using the formula:
[ \text{Conductance (℧)} = \frac{1}{\text{Resistance (Ω)}} ]
Thus, for a resistance of 5 ohms:
[ \text{Conductance} = \frac{1}{5} = 0.2 , \text{℧} ]
Mho is primarily used in electrical engineering, telecommunications, and physics to measure the conductance of materials and components. Understanding this unit is essential for designing circuits, analyzing electrical systems, and ensuring safety in electrical applications.
