Question

Three resisters 4 ohm , 6ohm, 8 ohm are combined in parallel what is the total resistance of the combination

Answer 1

$\tt\:formula \: \: : \: \boxed {\sf \frac{1}{ R} = \frac{1}{ R_1 } + \frac{1}{ R_2} + \frac{1}{R_3 } }$

so, by applying values

➸ 1/R = 1/4 + 1/6 + 1/8

➸ 1/R = (6+4+3)/24

➸ 1/R = 13/24

➩ R = 24/13Ω
