Parallel resistors have all have the same pd across them but the currents add, so: Itot = V / Rtot = V / R1 + V / R2 etc... then divide by V to get the familiar formula. Beware that the parallel formula is usually quoted as 1 / Rtot so they still have to …

The resistance should obey the standard rule for parallel resistors: 1/Rtotal = 1/R1 + 1/R2 . Note that the relationship for resistors in parallel is the total resistance is inversely proportional to the cross sectional area of the resistor.
