Expert Solution

Step 1

from below circuit

1.1) we will find equivalent,

voltage source replace by open circuit then equivalent resistance

$R_{e q} = 25 + 10 + (50 ∥ \{(45 ∥ 30) + (15 ∥ 60) + 20\}) R_{e q} = 25 + 10 + 50 ∥ \{\frac{45 \times 30}{75} + \frac{15 \times 60}{75} + 20\} R_{e q} = 25 + 10 + 50 ∥ \{18 + 12 + 20\} R_{e q} = 25 + 10 + 50 ∥ 50 R_{e q} = 25 + 10 + \frac{50 \times 50}{100} R_{e q} = 25 + 10 + 25 R_{e q} = 60 Ω$

Equivalent resistance as seen from source is 60 $Ω$
