Question

A wire has a resistance of 6.2. It is cut into two equal parts which are connected in
parallel, then the new resistance will be
A) 1.5 12.
B) 392
C) 6Ω
D) 1212

Answer 1

Answer:

a . 1.512 will be the correct answer

as resistance is directly proportional to length of the wire then if the length is half then the resistance of both the wires would be half of the initial wires that is 3.1 Ohm now these are connected in parallel so the resulted parallel combination of resistance should be 1.55 Ohm
