"I" stands for "Impetus", the original name for the strength of
an electrical current; that is, before Andre-Marie Ampere's Law
of 1825.

The mathematical symbol for each quantity is meaningful as well. The "R" for resistance and the "V" for voltage are both self-explanatory, whereas "I" for current seems a bit weird. The "I" is thought to have been meant to represent "Intensity" (of electron flow), and the other symbol for voltage, "E," stands for "Electromotive force." From what research I've been able to do, there seems to be some dispute over the meaning of "I." The symbols "E" and "V" are interchangeable for the most part, although some texts reserve "E" to represent voltage across a source (such as a battery or generator) and "V" to represent voltage across anything else.

Amps is the unit of meaure for current.
It is taken from the name André-Marie Ampère, one of the discoverers of electromagnetism.
Technically the unit is ampere, but is most often shortened to amps. Note that the units are not capitalized. If you are going to abbreviate 12 amps such as 12 A, then the letter A is capitalized.
Same goes for volts, 120 volts is abbreviated 120 V.

Amps are used as it is the measurement for current. Where i stands for current and can be got by dividing voltage by resistance.

*The letter “I” does indeed seem to refer to the intensity of current flow, measured in amperes.
An exploratory websearch for ‘intensity ampere’ gave 11,100 hits while ‘current ampere’ gave 78,000 hits, but ‘current intensity’ gave 1,250,000 hits suggesting that these two words appear on more page together.
“I” can refer to the impetus of electrical power also.
