Question

If 3 resistances of 3 ohm each are connected in parallel, what will be their total resistance?

Answer 1

Given: R₁ = 3 ohm

R₂ = 3 ohm

R₃ = 3 ohm

For resistors in parallel, total resistance is given by,

`1/R_"total" = 1/R_1 + 1/R_2 + 1/R_3`

`1/R_"total" = 1/3 + 1/3 + 1/3`

`1/R_"total"` = 1
