Question

when the resistance of 5 ohm 15 ohm and 60 ohm connected in parallel then the equivalent risistance will be​

Answer 1

Solution

Given :-

• 5 Ohm , 15 Ohm & 60 Ohm these are Resistance connected in parallel .

find:-

• Equivalent Resistance

Explanation:-

If r1 , r2 & r3 are connected in parallel.

Then, equivalent Resistance(R) be

$\boxed{\underline{\tt{\purple{\:\dfrac{1}{R}\:=\:\dfrac{1}{r_{1}}+\dfrac{1}{r_{2}}+\:\dfrac{1}{r_{3}}}}}}$

Keep all Values,

➡ 1/R = 1/5 + 1/15 + 1/60

➡1/R = (12 + 4 + 1)/60

➡1/R = 17/60

➡R = 60/17

➡R = 3.53 Ohm

Hence,

• Equivalent Resistance will be = 3.53 Ohmy
