	Subject - Total resistance jizza1 Total resistance: I have 3 resisters in parallel. How do I find the total resistance ? 4 Ohms 10 Ohms 12 Ohms Thanks!!!!!!! KSsparky 1/Rt = 1/R1 + R2 + R3.... So, your's would be 1/Rt = 1/4 + 1/10 + 1/12. You can either get to a common denominator or just use your calculator, just don't forget to invert your answer. Common denominator gets you 1/Rt = 15/60 + 6/60 + 5/60 so 1/Rt = 26/60 or 13/30 Therefore Rt = 30/13 or 2.3076923 ohms tony thrower Total Resistance = 1/ 1/R1 + 1/R2 + 1/R3 SOLUTION: 1/4=.25 1/10=.1 1/12=.083 .25+.1+.083=.433 1/.433 = 2.309 ohms Total Resistance will always be less than the least branch resistor in parallel circuits. tony thrower KSsparkey has the correct answer of 2.3076 ohms. Itried to type without my glasses or something ! Scott Vickrey Here's the formula for solving parallel resistance. Since you can't type a formula the way you want to, I'm starting a formulas collection so people can include them in their posts. You can see them here.
