wire is cut into five equal parts

1. = 1. 1. 1. 1. 1

Rp. = R/5. R/5 R/5 R/5. R/5

1= 5+ 5+ 5+ 5+ 5

R.p R. R. R. R. R take the l.c.m of R which will be R only

1 = 25

Rp. R.

Rp=25 ans

NaniNavanth: wrong answer is 2
varnikasom: no
varnikasom: ans is 25
varnikasom: u don't know anything
NaniNavanth: I think that u have more over confidence
NaniNavanth: keep that low for a while
NaniNavanth: when 50 ohm wire is cut into 5 equal parts...
then each part will have a resistance of 50/5-10
ohm.
Again when connecting parallelly, the total
resistance wil1 be..
1/R1/10+1/10+1/10+1/10+1/10
1/R 5/10
R=2ohm
varnikasom: bydway if u know the why are u asking ques
varnikasom: such a idoit
