Question

Resistance of a20centimeter long conductor in 20ohm the conductor is bent into circular loops and connected in the circuit calculate the resistant
resistance of each other

Answer 1

Answer:

A 10 ohms resistance when bent into the circle. The two points on the diameter will change it into 2 resistances of 5 ohms each, these both r will be in the parallel order. Hence the total resistance between these points will be 2.5 ohms 1/r=1/r1+ 1/r2

=1/5 +1/5

=2/5 ohms

So, final r=2.5 ohms.
