Question

plzz ans. my question ​

Answer 1

Answer:

Explanation:

Hey mate!!!!!!!!

Wire P has L/(A/2) = 2L/A Ω

Wire R has L/(A) = L/A Ω

When we compare both of them then : P:R = 2:1

Other way :

Both lengths are same : - Therefore resistances are same

Areas are different : a/2 , a

Area is inversely proportional to resistance so.

Resistance : 2 /a , a : 2:1

Hope this helps!!!!!!
