About Ohms
The ohm (Ω) is the SI derived unit of electrical resistance, equal to 1 volt per ampere (1 V/A = 1 kg·m²·A⁻²·s⁻³), named after Georg Simon Ohm who published V = IR in 1827. Common benchmarks: a standard earphone is 32 Ω, a coaxial cable has 50 or 75 Ω characteristic impedance, and a typical carbon-film resistor spans 1 Ω to 10 MΩ. The ohm is realised internationally via the quantum Hall resistance standard Rₖ = h/e² ≈ 25 812.807 Ω.
About Kilohms
The kilohm (kΩ) equals 10³ Ω, covering the most common range of discrete resistors in electronics. Pull-up and pull-down resistors are typically 1-10 kΩ; potentiometer tracks run 1-100 kΩ; input-bias resistors in transistor amplifiers and voltage-divider networks are almost always in the kilohm range. 1 kΩ = 10³ Ω = 10⁻³ MΩ.
