Question

The equivalent resistance across A and B is ( Wheatstone Bridge)​

Answer 1

Answer:

(d) 1•2 ohms

Explanation:

equivalent resistance

= {(2||2)+2} || 2

= {1+2} || 2

= 3 || 2

= (3×2) / (3+2)

= 6/5

= 1.2 ohms

option (d) 1.2 ohms is correct.

here || means parallel combination

and + means series combination

This is not a wheatstone bridge.

hope this helps you
