Question

A wire of resistance of 10 ohm, is divided into two halves and both halves are connected in parallel .The new resistance will be a) 1 ohm b)2 ohm c) 2.5 ohm d) 1.5 ohm​

Answer 1

Resistance of each half

<br> Since these two halves are in parallel, resultant resistance

.

Answer 2

Answer:

c)2.5 they are arranged parallel so resistance will change
