About Electrical Resistance
Electrical resistance is a fundamental property that measures how strongly a material opposes the flow of electric current. It is quantified in ohms (Ω), named after German physicist Georg Simon Ohm.
- Ohm (Ω) - The base SI unit of electrical resistance, defined as the resistance between two points when a constant potential difference of 1 volt produces a current of 1 ampere.
- Kiloohm (kΩ) - 1,000 ohms, commonly used for medium-range resistances in electronics.
- Megohm (MΩ) - 1,000,000 ohms, used for high resistance values in insulation and precision circuits.
- Gigaohm (GΩ) - 1,000,000,000 ohms, used in specialized high-resistance applications.
- Milliohm (mΩ) - 0.001 ohms, used for very low resistance measurements in power applications.
- Microhm (μΩ) - 0.000001 ohms, used for ultra-low resistance measurements in precision applications.
Understanding resistance is crucial for circuit design, power calculations, and electrical safety analysis in engineering applications.
Electrical Resistance Units
Electrical resistance units are essential for measuring and specifying the opposition to current flow in electrical circuits. These units span a wide range from ultra-low resistance measurements in power systems to extremely high resistance values in insulation testing.
- Ohm (Ω) — The fundamental SI unit of electrical resistance, universally used in circuit analysis and component specifications.
- Milliohm (mΩ) — Used for measuring very low resistances in power cables, contacts, and high-current applications where precision is critical.
- Microhm (μΩ) — Essential for ultra-precise measurements in research, calibration standards, and high-performance electronic components.
- Kiloohm (kΩ) — Commonly used in electronic circuits for resistors, sensors, and medium-impedance applications.
- Megohm (MΩ) — Applied in high-impedance circuits, insulation testing, and precision measurement equipment.
- Gigaohm (GΩ) — Used in specialized applications such as electrometer circuits, ion chamber measurements, and ultra-high impedance sensors.
- These resistance units enable engineers and technicians to accurately specify, measure, and analyze electrical components across all scales of electrical engineering, from nanoelectronics to power transmission systems.
