Question

give the answer for the above pic ​

Answer 1

Answer:

Answer is 2/5 ohm or 0.4 ohm

Explanation:

These are connected in Parallel so you can add their reciprocals to get reciprocal of effective resistance

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

= 2+2+1/2

= 5/2

therefore

Rp = 2/5 ohms

where Rp is Effective Resistance in Parallel
