Parallel Resistor Calculator

This parallel resistor calculator can calculate up to nine parallel resistance value, input the resistance on the boxes as labeled R1..R9 then select ohms, kilo ohms or megaohms in the dropbox. When input have been completed click on solve to calculate the total resistance. Check also standard resistor value for more info on standard resistor values

PARALLEL CIRCUIT

RT = 1 / (1/R1 + 1/R2 + 1/R3 + 1/R4 + 1/R5 + 1/R6 + 1/R7 + 1/R8 + 1/R9)
