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 Teraohms
The teraohm (TΩ) equals 10¹² Ω, the upper practical range of insulation resistance in laboratory and industrial measurements. Dry PTFE and fused quartz have volume resistivities of 10¹⁸ Ω·m or more, giving teraohm resistance for centimetre-thick samples; silicon photodiode dark resistance at room temperature can reach several TΩ; electrometer-grade guarded coaxial cables specify insulation resistance above 1 TΩ. 1 TΩ = 10¹² Ω = 10³ GΩ.
