Question

seven resistors each of resistance 5ohm are joined end to end to form a heptagon abcdefg find the equivalent​

Answer 1

Explanation:

Baki bhai tu khud he smajh gya

5×4 = 20 Ohm in series through path APB

5×3 =15 Ohm also in series through path AQB

now APB and AQB are in parallel

1/20+1/15= 7/60 = 1/Rp

So Rp=60/7 Ohm Answer
