Question

a wire is resistance 5 ohm belt through the circle what is the effective resistance between the two points at the end of any diameter of the circle​

Answer 1

Answer:

The diametrically opposite points divides the resistance into half of the total resistance.

Resistance of each semi circle R

1

=R

=

5

=2.5 Ω

These resistance are connected in parallel.

So, equivalent resistance R

2.5×2.5

=1.25Ω
