The ohm (symbol: Ω, the uppercase Greek letter omega) is the unit of electrical resistance in the International System of Units (SI). It is named after German physicist Georg Ohm (1789–1854).
The Om symbol, with epigraphical variations, is also found in many Southeast Asian countries. In Southeast Asia, the Om symbol is widely conflated with that of the unalome; originally a representation of the Buddha's urna curl and later a symbol of the path to nirvana, it is a popular yantra in Southeast Asia, particularly in Cambodia and Thailand.
The symbol for the highest power level of a PSI attack in the Mother/EarthBound games; A symbol used by U.S. citizens in the 1960s & 1970s to denote resistance to the U.S. war in Viet Nam. Adapted from the SI unit for electrical resistance. [20] It's used along with Alpha in the Alpha and Omega, a Christian symbol. [21]

The siemens (symbol: S) is the unit of electric conductance, electric susceptance, and electric admittance in the International System of Units (SI). Conductance, susceptance, and admittance are the reciprocals of resistance, reactance, and impedance respectively; hence one siemens is equal to the reciprocal of one ohm (Ω −1) and is also referred to as the mho.
The conventional symbol for current is I, which originates from the French phrase intensité du courant, (current intensity). [5] [6] Current intensity is often referred to simply as current. [7] The I symbol was used by André-Marie Ampère, after whom the unit of electric current is named, in formulating Ampère's force law (1820). [8]
