SOLUTION: If three electric resistors with resistances R1, R2, and R3 are connected in parallel, then the total resistance R for the circuit shown in the figure is given by R = 1%1/R1+1/R2

Question 939452: If three electric resistors with resistances R1, R2, and R3 are connected in parallel, then the total resistance R for the circuit shown in the figure is given by
R = 1%1/R1+1/R2+1/R3
Represent this compound fraction as a simple fraction.

If three electric resistors with resistances R1, R2, and R3 are connected in parallel, then the total resistance R for the circuit shown in the figure is given by
R = 1%1/R1+1/R2+1/R3
It's 1/R = 1/R1 + 1/R2 + 1/R3
1/R = (R1*R2 + R1*R3 + R2*R3)/(R1*R2*R3)
OR R = R1*R2*R3/(R1*R2 + R1*R3 + R2*R3)
