Question

Three identical resistances are first connected in
series and then in parallel. The ratio of resultant
resistance of first combination to the second will be.​

Answer 1

Answer:

Explain Taking three 2ohm resister In parallel =2/3ohm In series =6ohm Ratio =parallel to series =2/3×6 =1/9

Answer 2

Explanation:

1

Two identical resistors are first connected in parallel then in series. What will be the ratio of resultant resistance of the first combination to the second?

Well..let’s consider R and another R (obvio coz, they are identical)

R(in parallel):

1/Rp = 1/R + 1/R = 2/R

Rp=R/2

R(in series):

Rs=R+R=2R

now, Rp:Rs= R/2:2R

=1:4
