This routines provides for solving all 12 Ohm’s Law formulae. The routine asks for the 3 variables required in a formula with the first one being the variable to solve, the second is the first known value, and the third is the second known value. Using I – Amps, E – Volts, P – Watts, R – Ohms, the variables are entered in the form “P, I, E”. The routine will then ask for the values of “I, E” in the form of “0.2, 110”. Note that all items are separated by a comma and a space (“, “).
