Should Voltage Be Capitalized?

1 Ω = 1 V/A.

Thus the names of all units start with a lower-case letter, except at the beginning of a sentence or in capitalized material such as a title.

In keeping with this rule, the unit symbols for Ampere is a capitalized “A” and Volt is capitalized “V” because both unit names are based on the names of scientists.

Is Volts V or V?

The unit of voltage is the volt, named after Volta, and abbreviated to V. The unit of current is the ampere, named after Ampère, and abbreviated to A.

Should AC and DC be capitalized?

In general, most abbreviations of technical terms are capitalized, but there are notable exceptions such as ac, dc, and rms. Note that periods are not used and the abbreviation is the same regardless of whether it is used as a noun or an adjective.

What units make up a Volt?

The unit of current is the ampere (A), and means one coulomb per second. The unit of potential difference is the volt (V), and means one joule per coulomb.
