How many types of Ohm's Law are there?

Answer
There is fundamentally one Ohm's Law, but it can be expressed in three different forms (V = I × R, I = V ÷ R, and R = V ÷ I) depending on which variable you're solving for. Some people also refer to the "power triangle" formulas that combine Ohm's Law with power calculations, but the core principle remains the same.
