Answer 1

Answer:

7/4 Ω

Explanation:

Near the point A, the three resistors are in parallel

So, Rp=R/3

This combined resistor is in series with the next resistor,

So, Rs=4R/3

Now, this combined resistor is in parallel with resistor below,

 Rp=4R²/7R

∴ 4R²/7R=1

         4R²=7R

      ∴R=7/4 Ω
