Question

Three resistance of 10 ohms 15 ohms and 30 ohms are connected in a parallel the total resistance of combination

Answer 1

Answer:

total resistance =

1/10+1/15+1/30

= 5 ohms

Explanation:

Answer 2

Answer: 5 ohms

Explanation :

Let the total resistance be R . Let r1 = 10 ohms , r2 = 15 ohms and r3 = 30 ohms.

As they are in parallel hence ,

1/R = 1/r1 + 1/r2 + 1/r3

=) 1/R = ( 1/ 10 + 1/15 + 1/30 )Ω

=) 1/R = ( 3+2+1)/30 Ω

=) 1/R = 1/5 Ω

=) R = 5 Ω

Hope you have understood.
