Question

when number of resistances are connected in parallel then the effective of its combination___​

Answer 1

Answer:

when number of resistances are connected in parallel then the effectiveness of its combination decreases

Explanation:

Formula for resistor  in parallel:

1/Rₙ = 1/R₁ + 1/R₂ + 1/R₃

For an illustration,

let us take resistors of equal resistance x

so,

1/Rₙ = 1/x +1/x + 1/x

1/Rₙ = 3/x

⇒Rₙ = x/3

Here, the numerator states the actual resistance and denominator states the number of resistance.

here we can see R α No. of resistance

So the effectiveness of the combination reduces when connected in parallel.
