Tool to convert letters to numbers and vice versa. The letter-to-number cipher consist in replacing each letter by its position in the alphabet
The relationship between voltage, current, and resistance is described by Ohm's law. This equation, i = v/r, tells us that the current, i, flowing through a circuit is directly proportional to the voltage, v, and inversely proportional to the resistance, r.
Is there multiple choice? if not it would be a Space Lander.
