What does the I in Ohm's Law mean?

Question

I know it stands for current, but what does the letter itself mean? I mean volts is V, resistance is r while tis unit sign is omega...what does I stand for?

Answer 1

I is current in amps.

What is the question? I means current, you already know that.

The letter is a bit arbitrary sometimes. P is momentum, or power. L is inductance. and lots more...

Answer 2

current

Answer 3

I or i stands for current.

it is from the french word, "Intensite".

Answer 4

I refers current

Answer 5

Princess was correct.

In 1820 the French mathematician André-Marie Ampère developed a theory and had it published. In the publication he used i for "intensité de current" (translates as intensity of current). The symbol for the intensity of current (now just called current in English) has been i ever since.

The units for current are called amperes (or just amps for short). One ampere is equivalent to one coulomb of charge per second.

Answer 6

im 100% sure that  I stands for Intensity of the current

Answer 7

I'm not 100% sure, but I believe the "I" comes from the term "International Ampere".

According to Wikipedia,

The "international ampere" was an early realization of the ampere, defined as the current that would deposit 0.001118000 grams of silver per second from a silver nitrate solution. [6] Later, more accurate measurements revealed that this current is 0.99985 A.
