The combined resistance of two resistors R1 and R2 in a
parallel circuit is given by the formula
Rt= 1 divided by 1/r1+1/r1 simplify the formula.
:
Rt = 1%2F%28%281%2Fr1%29+%2B+%281%2Fr2%29%29
:
Put the two fractions in denominator, over a single common denominator; (R1*R2)
Rt = 1%2F%28%28r2%2Br1%29%2F%28r1%2Ar2%29%29%29
:
Invert the dividing fraction and multiply
Rt = 1 * %28%28r1%2Ar2%29%29%2F%28%28r1%2Br2%29%29
Which is:
Rt = %28%28r1%2Ar2%29%29%2F%28%28r1%2Br2%29%29
