About Megaohms
The megaohm (MΩ) equals 10⁶ Ω, the scale of insulation testing and high-impedance analogue circuit design. Insulation testers (meggers) measure cable and motor winding insulation from 0.1-1000 MΩ; pH electrode output impedance is 10-500 MΩ; precision op-amp feedback networks use 1-10 MΩ resistors to set very high signal-source impedance. 1 MΩ = 10⁶ Ω = 10³ kΩ.
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.
