Ohm's Law and Resistance Conversion

Ohm's law, discovered by Georg Ohm in 1827, is a fundamental principle in electronics. It establishes a direct relationship between voltage, current, and resistance:

Voltage (V) = Current (I) × Resistance (R)

Rearranging the formula, we get:

Resistance (R) = Voltage (V) / Current (I)

These formulas allow for easy conversion of ohms based on known values of voltage and current.
