The volt per ohm (V/Ω) is a derived unit of electric current, representing the flow of electric charge in relation to the resistance in an electrical circuit. This unit is crucial for understanding Ohm's Law, which states that current (I) is equal to voltage (V) divided by resistance (R). Therefore, V/Ω is equivalent to amperes (A), making it a vital unit in electrical engineering and physics.
The volt per ohm is standardized within the International System of Units (SI), where:
The concept of electric current has evolved significantly since the 19th century, with pioneers like Georg Simon Ohm and André-Marie Ampère laying the groundwork for our understanding of electricity. The volt, named after Alessandro Volta, and the ohm, named after Georg Simon Ohm, have become fundamental units in electrical science. The relationship between these units has been pivotal in developing modern electrical systems and technologies.
To illustrate the use of the volt per ohm, consider a circuit with a voltage of 12 volts and a resistance of 4 ohms. Using Ohm's Law: [ I = \frac{V}{R} = \frac{12V}{4Ω} = 3A ] Thus, the current flowing through the circuit is 3 amperes, which can also be expressed as 3 V/Ω.
The volt per ohm is primarily used in electrical engineering, physics, and various applications involving electrical circuits. It helps engineers and technicians calculate current flow, design circuits, and troubleshoot electrical issues.

The milliohm (mΩ) is a unit of electrical resistance in the International System of Units (SI). It is equal to one-thousandth of an ohm (Ω), which is the standard unit for measuring electrical resistance. Understanding milliohms is crucial for professionals in electrical engineering, electronics, and related fields, as it allows for precise measurements in low-resistance applications.
The milliohm is standardized under the SI unit system, ensuring consistency and reliability in electrical measurements. It is commonly used in various applications, including electrical circuits, power systems, and electronic devices, where low resistance values are prevalent.
The concept of resistance was first introduced by Georg Simon Ohm in the 1820s, leading to the formulation of Ohm's Law. As technology advanced, the need for more precise measurements in low-resistance scenarios emerged, giving rise to the milliohm as a practical unit. Over the years, the milliohm has become essential in fields such as telecommunications, automotive engineering, and renewable energy systems.
To illustrate the use of milliohms, consider a scenario where a circuit has a total resistance of 0.005 Ω. To convert this to milliohms, simply multiply by 1,000: [ 0.005 , \text{Ω} \times 1000 = 5 , \text{mΩ} ] This conversion is vital for engineers who need to work with low resistance values accurately.
