$\large\bf\underline {To \: find:-}$

• we need to calculate Equivalent resistance in the given circuit.

$\huge\bf\underline{Solution:-}$

In 1st figure

AB , BC and AD are connected in series,

So,

→ Rs = 1Ω + 1Ω + 2Ω

→ Rs = 4Ω

Now,

In second figure Rs and DC are connected in parallel,

So,

→ 1/Rp = 1/Rs + 1/4

→ 1/Rp = 1/4 + 1/4

→ 1/Rp = 2/4

→ 1/Rp = 1/2

→ Rp = 2Ω

Now ,

In Third figure all r resistors are connected in series,

Then Total resistance R :-

→ R = Rp + 2Ω + 1Ω

→ R = 2Ω + 3Ω

→ R = 5Ω

Hence,

Equivalent resistance of given circuit is 5Ω
