Question

A wire of uniform resistence 5ohms is bend to form a circle .what would be the value of effective resistance across its any diameter

Answer 1

TOTAL NO OF UNIFORM RESISTANCE 1÷5

1÷5

=2÷10

=5

Answer 2

Answer:2.5 ohms

Explanation:

hey sup ,

The explanation is fairly simple ,

so basically whenever the wire is bent into a circle there will be two resistors connected in parallel each having a resistance of 10 ohms so now we will apply the formula for resistors in parallel,

1/Req = 1/r1+ 1/r2

          = 2/10

but r eq = 10/2=5ohms

hope it helps u
